Van Goghs Use of Color Crafted by Van Gogh and his utilization of shading have regularly been concentrated sequentially showing the move in his use of hues from his initial works of art, which were dim and cynical, to the compositions of his develop vocation, where he has utilized lighter tones and more splendid colors.Advertising We will compose a custom paper test on Van Goghââ¬â¢s Use of Color explicitly for you for just $16.05 $11/page Learn More In the later stage, Van Gogh utilized reciprocal shading plan, which was an unmistakable move from the old style treatment of hues. This paper will look into two artistic creations, The Sower and The Night Cafã ©, and exhibit the unmistakable style Van Gogh followed to utilize shading for his artworks. Expressive utilization of hues in particular reciprocal plans has overwhelmed a significant number of the showstoppers made by Van Gogh. His correspondences to his sibling during the 1882-85 exhibit his fixation on the utilization of shading in his work. The y exhibit that Van Goghââ¬â¢s concern and differentiation between conceals, tones, tone, and brilliance of shading, which framed the mental premise of hues and topics of his artistic creations. The utilization of correlative hues, which turned into the mark of Van Goghââ¬â¢s style, assisted with escalating the common impact of the shading plan in the works of art. Van Gogh utilized essential hues and differentiating tints to build immovability and profundity of his works of art: These things that are pertinent to integral hues, to the concurrent differentiating and the shared downgrading of reciprocal hues, are the first and most significant issue: the second is the common impact of two comparative hues, for example, carmine and vermilion, or a pink-lilac and a blue-lilac. (Van Gogh Letter # 428, dated Oct. 1885. (Bekker and Bekker) The utilization of essential hues and the utilization of their correlative hues, otherwise called optional hues, is a fundamental procedure utiliz ed for impressionistic artistic creation. At the point when an essential shading is set against an integral shading, it makes a differentiating shading plan, making a ground-breaking impact. Van Gogh abused this method of making a solid impact in his artistic creation through juxtaposition of essential and correlative hues. Van Goghââ¬â¢s interest for reciprocal hues strengthened as he moved his concentration from Dutch style to artworks that are more impressionistic.Advertising Looking for exposition on workmanship and plan? How about we check whether we can support you! Get your first paper with 15% OFF Learn More Gayford (179) shows Van Goghââ¬â¢s uplifted enthusiasm for hues, which made an emblematic language for the maestro. In another correspondence to his sibling Theo, Van Gogh communicated his expanding fixation on hues: ââ¬Å"Yesterday evening an exceptional wonderful dusk of a baffling, wiped out citron shading â⬠Prussian blue cypresses against trees with dead l eaves in a wide range of broken tones with no spotting with brilliant greens.â⬠(Gayford 179) Thus, hues make a representative language for Van Gogh, which helped his to decide the impact that needed to make in his artistic creations. Given this comprehension of Van Goghââ¬â¢s theory of shading, the exposition at that point proceeds onward to break down two of his artworks and the treatment of hues in them. The Sower exhibits a man striding over a wheat field, with outstretched arms, show up in a significant number of Van Goghââ¬â¢s artistic creations and representations. Rationally, it has frequently been deciphered as the recharging of life; notwithstanding, in this article we will talk about the utilization of reciprocal shading plan of the canvases. The specific picture that is examined in this exposition was painted in 1888, which stands apart from every single other work of art of sowers and makes an interesting impressionistic making of the cycle life in full summe r (The Sower is appeared in figure 1 beneath). Figure 1: The Sower, 1888 The Sower, painted predominately in yellow and violet shows the utilization of integral hues by Van Gogh. Yellow is an essential shading that is situated against violet, one of its supplements, and a blend of the other two essential hues, red and blue. Despite the fact that craftsmen knew about the impact two integral hues could make, nobody before Van Gogh explored different avenues regarding it.Advertising We will compose a custom article test on Van Goghââ¬â¢s Use of Color explicitly for you for just $16.05 $11/page Learn More Primary hues, when compared with reciprocal hues, make a vibration and radiance that is in any case out of reach. Subsequently, when yellow is utilized against violet, it makes more prominent splendor and immaculateness of shading than when painted with some other hues. So also, violet appears to be all the more enthusiastic and vivacious when set against yellow. The Sower was paint ed when Van Gogh was living in Arles, in June 1888. The first Sower by Millet from which Van Gogh drew motivation or his Sower accepted that Millet made an artistic creation in ââ¬Å"colorless grayâ⬠and needed to make a composition of the sower with hues (Bekker and Bekker). So as to comprehend shading contrast, think about setting orange against blue and orange against green. Orange is blueââ¬â¢s supplement where blue is an essential shading and orange is an auxiliary shading made through blending of the other two essential, red and yellow. Consequently, the impact of brilliance when orange and blue are utilized together is more prominent than when orange and green are utilized, wherein both are auxiliary hues. Also, the orange when put with green appear to be darker, very nearly an alternate shading. Subsequently, it very well may be seen that hues can change their shade and splendor relying upon the hues with which they are utilized. In addition, hues can't be utilized uniquely, without considering different hues that are utilized. Hues can't be decided in confinement. Subsequently, it is essential to comprehend what hues are utilized alongside the others and what influence it makes in the artistic creations. Information on hues turns into the most significant factor while examining Van Goghââ¬â¢s structure so impressionistic artwork. The artwork of the yellow and violet together as a declaration of light and obscurity in the field is an extraordinary case of utilization of reciprocal hues in works of art. This aided in escalating the splendor, immersion, and profundity of the canvas. Van Gogh portrayed his 1888 creation propelled from Milletââ¬â¢s painting, in one of his letters, as ââ¬Å"painting from Milletââ¬â¢s drawings is more similar to making an interpretation of them into another dialect than replicating themâ⬠(Metzger and Walther 272). The hues utilized in the artistic creation got suggestive of his feelings and emotions. The hues showed the prevailing state of mind of the painter. The Night Cafã © is a graceful articulation through hues, which exhibits the harsher real factors of present day life. Van Goghââ¬â¢s fixation on hues heightened from 1885 until his passing in 1890, resounding in his letters to his sibling Theo. Every one of the letters is suggestive of the immersion, tint, and force of the hues from his palette. In depicting the Night Cafã © (figure 2) in his letter to Theo, Van Gogh partners energy with the utilization of two integral hues â⬠red and green:Advertising Searching for article on workmanship and plan? We should check whether we can support you! Get your first paper with 15% OFF Find out More Iââ¬â¢ve attempted to communicate the awful interests of humankind with red and green. The room is dark red and dull yellow, with a green billiard table in the center; there are four lemon yellow lights throwing an orange and green glowâ⬠¦ In my image of the night cafã ©, Iââ¬â¢ve attempted to pass on the feeling that the cafã © is where one goes to demolish goes distraught, perpetrates violations. Iââ¬â¢ve attempted to communicate the forces of haziness, as it were, in this plunge of a bar, through differences of sensitive pink, dark red, wine red, and delicate Louis XV green and Veronese green, conversely with hard green-yellows and blue-greens â⬠this in the midst of a diabolical heater of pale sulfur. (Letter#533, Bekker and Bekker) The above depiction of the composition as communicated through Van Goghââ¬â¢s words exhibit the utilization of corresponding hues in the artistic creation, and the explanation behind the sue of the hues in their integral best. Lif eââ¬â¢s juxtaposition is communicated through the restrictions of shading that makes life just as his artistic creations so throbbing. In the Night Cafã © Van Gogh has communicated the battle of life through the juxtaposition of the two integral hues â⬠red and green. The violet and blue utilized in the canvas portrays pity and terribleness of present day nightlife, and Figure 2: The Night Cafã © The work of art shows most extreme immersion of hues, where hues like red and green has been utilized with no trace of color or shade. In the Night Cafã ©, Van Gogh utilized shading in its most perfect structure against its similarly unadulterated correlative. This isn't found in The Sower, where the hues were utilized emblematically, yet not its most perfect tint. The utilization of unique tint in the Night Cafã © sets is separated from different canvases, despite the fact that the strategy utilized in both the photos are comparative. All things considered, both the image resonat es with the diabolical heater of life however the utilization of yellow, which has been utilized to portray the sun in The Sower and the lights in The Night Cafã ©. The contrast between the two works of art is that the first is a delineation of congruity of life while that of the cafã © depicts a repulsive presence. Bekker, K.G. also, A.Y. Bekker. 2009.

Androstenedione Essay Example For Students
Androstenedione Essay This previous year a ton of things have occurred on the planet. President Clinton might be indicted. Our administration attempted to by and by take over Sadaam Hussein. What's more, Mark McGwire hit 70 grand slams to break Roger Maris record of 61. During this uncommon occasion in the baseball world, one thing of doubt blurred the whole achievement. During a meeting that he was giving straightaway to his storage, a columnist saw a jug on the first rate. This jug was loaded up with a nourishing pill titled androstenedione, a lawful dietary supplement that is a testosterone-creating drug that enables the body to fix itself after exercises. This repairment, thus, helps the individual taking it fabricate muscle quicker. A few avid supporters, and some who are not, state that McGwires record ought to be limited because of the utilization of this pill. I am definitely not one of those individuals. What he did for this present year was an individual achievement and while the andro may have helped a bit, Mark did this through long periods of difficult work in the batting confines. As a thin new kid on the block in 1987, McGwire figured out how to take 49 balls out of the recreation center. I believe that 11 additional years involvement with the association could give a player the experience to chalk up another 21 dingers. Presently in truth, I can see a few cynics focuses. Androstenedione is a supplement that has been prohibited by various games associations worlwide: the NFL, NCAA, and the International Olympic Committee for instance. However, Major Association Baseball isn't one of these associations. So why at that point should his record be nixed for disrupting a norm that doesn't have any significant bearing in his game? The appropriate response is he shouldnt. Imprint McGwire is a great competitor who bettered his game by adhering to the principles. He did literally nothing incorrectly in getting this once thought of ridiculous record. Another perspective to take a gander at is that Sammy Sosa likewise had a gigantic year. This Chicago Cub hit 66 grand slams this year and he has never contacted androstenedione. How hard is it for a kindred slugger to hit 4 more? Not excessively troublesome on the off chance that you are as high a bore player as McGwire. Muscle building supplements have been utilized for quite a long time in master and school athletic programs. Creatine, likely the most well known, is utilized by practically every major school in the nation. Indeed, even your normal weight lifter utilizes it. Androstenedione is only one stage higher on the dietary scale, and just by a division. A articulation was given by the Cardinals clinical staff concerning androstenedione when the alleged outrage surfaced. Presently, there is a plausibility that it might be slightly one-sided however remember that the women and men of their word that gave this announcement are still specialists. Androstenedione is a characteristic substance, which is a characteristic antecedent result of testosterone. It has no demonstrated anabolic steroid impact nor noteworthy reactions. It animates slight increment levels for a brief timeframe (60 minutes). Taken around one hour before exercises, it might make ones exercise increasingly productive. Due to ebb and flow investigate that locks narrative proof of any unfavorable symptoms, the Cardinals clinical staff can't question Marks decision to utilize this legitimate and over-the-counter enhancement. In the event that many specialists more than once shields androstenedione as innocuous and the FDA supports its utilization, why all the debate? Creatine is essentially something very similar and is utilized on a substantially more boundless premise, yet nobody addresses its utilization. Why? I imagine that mostly the reason might be on the grounds that Mark McGwire is so acceptable thus amazing. Roger Maris record was never at any point undermined as of recently. Living in the sort of nation we do, individuals expected to locate an awful side to everything that is unadulterated. Indeed on the off chance that no standard was broken, the general population charges in any case. In the event that legitimate muscle upgrading items were banned and everybody who utilized them had their records renounced, the standard by which we measure athletic significance would be extensively lower. .u4915a9f1091366967321c27e996bfd95 , .u4915a9f1091366967321c27e996bfd95 .postImageUrl , .u4915a9f1091366967321c27e996bfd95 .focused content zone { min-stature: 80px; position: relative; } .u4915a9f1091366967321c27e996bfd95 , .u4915a9f1091366967321c27e996bfd95:hover , .u4915a9f1091366967321c27e996bfd95:visited , .u4915a9f1091366967321c27e996bfd95:active { border:0!important; } .u4915a9f1091366967321c27e996bfd95 .clearfix:after { content: ; show: table; clear: both; } .u4915a9f1091366967321c27e996bfd95 { show: square; change: foundation shading 250ms; webkit-progress: foundation shading 250ms; width: 100%; mistiness: 1; progress: obscurity 250ms; webkit-change: haziness 250ms; foundation shading: #95A5A6; } .u4915a9f1091366967321c27e996bfd95:active , .u4915a9f1091366967321c27e996bfd95:hover { darkness: 1; change: murkiness 250ms; webkit-change: haziness 250ms; foundation shading: #2C3E50; } .u4915a9f1091366967321c27e996bfd95 .focused content territory { width: 100%; position: relative; } .u4915a9f1091366967321c27e996bfd95 .ctaText { outskirt base: 0 strong #fff; shading: #2980B9; text dimension: 16px; textual style weight: intense; edge: 0; cushioning: 0; content embellishment: underline; } .u4915a9f1091366967321c27e996bfd95 .postTitle { shading: #FFFFFF; text dimension: 16px; textual style weight: 600; edge: 0; cushioning: 0; width: 100%; } .u4915a9f1091366967321c27e996bfd95 .ctaButton { foundation shading: #7F8C8D!important; shading: #2980B9; fringe: none; fringe sweep: 3px; box-shadow: none; text dimension: 14px; textual style weight: striking; line-tallness: 26px; moz-outskirt span: 3px; content adjust: focus; content design: none; content shadow: none; width: 80px; min-tallness: 80px; foundation: url(https://artscolumbia.org/wp-content/modules/intelly-related-posts/resources/pictures/basic arrow.png)no-rehash; position: outright; right: 0; top: 0; } .u4915a9f1091366967321c27e996bfd95:hover .ctaButton { foundation shading: #34495E!important; } .u4915a9f109136 6967321c27e996bfd95 .focused content { show: table; stature: 80px; cushioning left: 18px; top: 0; } .u4915a9f1091366967321c27e996bfd95-content { show: table-cell; edge: 0; cushioning: 0; cushioning right: 108px; position: relative; vertical-adjust: center; width: 100%; } .u4915a9f1091366967321c27e996bfd95:after { content: ; show: square; clear: both; } READ: Jeff Bezos Essay Whether or not or not Mr. McGwire utilized a muscle improving item or not, he achieved a dynamite accomplishment.

How Do Renewable Energies More Efficient Than Coal
Throughout time, we have heard how renewable energies are more efficient than coal. They are cleaner, better for the environment, and allegedly more cost efficient. How cost efficient fossil fuels are may depend on which side you look at ââ¬â the electric company or people and businesses. For an electric company, it is very cost efficient. However, it will take time to see the efficiency to a business. Electric companies have to build or change the plants they currently have in order to meet the needs of the new system, whether it be wind, solar, etc. The ââ¬Å"war on coalâ⬠came too quickly; as we will detail below, you cannot quit using your main source of heat to generate electricity and expect the country to run as it has before. Changing takes time and money. If power plants make minuscule changes to their production and facilities, electric companies will show a small fixed and variable cost in the income statement. Even if they have to produce a new facility, the benefits will outweigh the cost, and the new plants will be paid for in a short amount of time. The resident or business installs the solar panels, so the only cost the electric company has are the loss from the rebates. With this, they will not have to change their facilities, and yet they will still make somewhat of a profit. Immediately expensing the cost of building a new electrical system, by solar panels or through a geothermal system, for example, will not immediately affect how much electricity is produced.Show MoreRelatedRenewable Fuels And The Energy Issue1583 Words à |à 7 PagesInvestigating whether a renewable fuel produces the same level of energy as an equivalent amount of nonrenewable fuel would be beneficial to help save Earthââ¬â¢s natural resources and i s a very relevant and important science project.

The Reasons For The Europeans Voyage Of Exploration At The...
The reason for the Europeans voyage of exploration at the end of the Sixteenth Century was because in the past ages the Europeans thought that the earth was flat. In the exploration of the world they had known the world to be the ââ¬Å"Age of Discoveryâ⬠. They only knew about the land that was close to their home and country. They wanted to explore the world by sea so that could search for new trading partners, new goods, and new trading routes. The major differences among the colonists in the Chesapeake, Middle Colonies, and New England were there governance, economy, social structure, and the American Indians. In the Chesapeake, Virginia was governed by a royal charter until 1624 and Maryland was a proprietary colony which gave the Calvert all the right to appoint governors and also control the government. Economically, Virginia and Maryland big cash crop between the two states were tobacco. Social structure minority consisted of mostly free men and women, as the majority consisted of laborers and servants, which they became free after a certain period of time. Around the 1700s slaves had become a wide proportion of the southern population. The social and political was very much similar to England. The American Indians in the 1640, being a native population in Virginia decreased from 20,000 to 10,000. By 1670s only about a dozen tribes and 2,000 Native American remained in the colony.

Life Cycle Analysis for Lithium-ion Battery Production and Processing
Question: Discuss about the Life Cycle Analysis for Lithium-ion Battery Production and Processing. Answer: Introduction The debate on the impact of automotive emissions on environment has been escalating over the past decades. The Olofsson (1) estimates that transportation sector emits 16% of CO2, which needs drastic reduction. Different legislative stipulations have been passed to facilitate the reduction of the emissions: for example, Euro-6 and Euro-VI emission stipulations for light and heavy vehicles respectively were introduced in 2014 to regulate the emission of NOx among the new models (1). With increasing fear on debilitation of fossil fuel and pressing issues of energy security, there is a growing interest on the need to improve energy efficiency. Based on the recent developments from auto industry and the government, Gaines et al (2) observe that batteries are considered to be the most suitable in manufacturing as well as marketing electric-drive cars; both plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (p.3). According to Gaines et al (2), effective installation of viable battery systems for electric-driven vehicles has the efficacy to minimize fossil fuels consumption as well as reducing greenhouse emissions (GHG) (p.3). Nevertheless, so much is yet to be established insofar as electric-drive performance and impacts of batteries on their efficiencies is concerned. Batteries that contain high specific energy and peculiar life cycle remain the fundamental elements that will facilitate successful manufacture of electric-drive vehicles, however. More importantly, scientists consider lithium-ion batteries (Li-ion) to be the main factor that will enhance the penetration of the technology. Nelson et al (3) attest that the nature of electric-drive market is multi-faceted in terms of engineering execution, consumer preference, and affordability (2). Essentially, the impact of such vehicles on the environmental performance is among the key driving factors towards their developments. On the crux of the matter is emission and energy efficiency of battery cells. However, there are some existential trade-offs that are inevitable when deployment of electric-drive vehicle will be effected. The energy trade-off necessitates quantification in developing conventional cars by lightweight materials, which reflects the balance between extra energy incurred in developing lightweight material and the fuel saved in driving it, due to the reduced weight (3). Like any other product system, the burdens of life-cycle batteries emanates from different life-cycle phases, for example, during production of the material, during production and the usage of the battery, or during battery recycling phase. Adequate information on challenges incurred when developing lithium component materials like iron phosphate, lithium cobalt dioxide, lithium hexafuolorophosphate, and lithium nickel dioxide including some process information is still lacking. Due to this absence, estimation of the production energy as well as emissions with regard to the life cycle has been made difficult. This paper provides an overview on the impacts of lithium-ion life cycle batteries. The paper focuses on the burden of battery recycling to the production of active materials, which have not been properly characterized hitherto. Goal The objective of this paper is to examine the life cycle impacts of Lithium-ion batteries. Special interest is placed on the burden of the production process and recycling process of Li-ion battery cells. Due to the scarcity of materials used in the manufacturing of Li-ion, the paper dissects recycling processes that have the efficacy to underscore energy efficiency and reduce emissions. Life Cycle Assessment Generally, LCA method is used to dissect the environmental consequences of an entire life cycle that involves production of a given product or service (1). The most common areas, according to Olofsson (1) where the knowledge of LCA is applied include product development, production processes, and waste management (p.2). The method has become increasingly significant for environmental communication. On product development, LCA is facilitates assessment of potential hotspots of a product life cycle and improves development of eco-design, which provides a springboard to identify the most optimal design at the conceptual phase (1). In order to realize the optimal design it is imperative to avoid hazardous materials, cut down the energy used in production stage, use light materials and high quality features to encourage weight minimization, and use materials that can be upgraded, repaired, recycled, and reused. Functional Unit Rechargeable battery The use of batteries to develop small-scale electric sources and portable devices has been on upward trajectory. Depending on their capacities, batteries can be used to power a variety of electronic devices and automotive. Young (4) observes that the capability of rechargeable battery to store chemical energy and produce electric energy, as well their durability feature has made it more prevalent in todays society. Olofsson (1) asserts that when battery cell is connected to an external circuit, oxidation and reduction reactions occur at the negative and positive electrodes respectively (p.4). Consequently, the electrons flow towards and the external circuit while the ions flow within electrodes via electrolyte. An electric insulator separates the anode and the cathode, and facilitates the flow of electrons to the external circuit only. The insulator also slows down the reaction process when the cell is connected to an external source. The pendulum of the amount of energy that the bat tery has swings from state of charge (SOC) to discharge, depending on how the battery is used (4). Materials available in Lithium-ion batteries/ components Li et al (5) state that LCA is the most appropriate method when it comes to comparing alternative technological systems, since it entails broad assessment of life cycle of a product or a service, including production of materials, service provision, and maintenance. The paper focuses on quantitative elements of LCA. The paper relies on Gaines et al analysis of GREETZ 2.7 model to examine impact of Lithium-ion batteries. Dunn et al (6) hold that Li-ion batteries have been considered efficient in contemporary as well as future battery technology because they quintessentially have high volumes of energy and gravimetric power. The interplay flow of lithium ions between anode and cathode forms the central basis of Li-ion batteries mechanism. The electrodes are made up of conducting foil. Between the electrodes lies electrolyte. The active component of electrode is made of intercalation materials that have the efficacy to host Li-ions without dismantling their structures. Most chemistries prefer using graphite to make cathode material (4). Production of active materials: Lithium Carbonate Generally, Lithium is extracted from spodumene or brine-lake deposits (2). Due to energy consumption and economic purposes, brine-lake resources are considered to be more efficient and have the capacity to meet the surging demand of for Li-ion automotive batteries. During the extraction process, extensive pumping of brine from brine well into a solar evaporation pond occurs and the brine is left to concentrate (2). Once sufficient evaporation and concentration has occurred, pumping of brines to successive ponds follows until crystallization and precipitation of sodium chloride and other salts takes place (4). After pumping the brine into 4-5 ponds, addition of slake lime to precipitate calcium and magnesium salts follow. This results to the production of magnesia and gypsum. When more slake-lime is added to the successive ponds, depletion of calcium, magnesium, and sodium salts occurs until brine with capacity of 0.5% lithium can be redirected to a manufacturing plant that extracts l ithium from lithium carbonate. Spodumene Another source of lithium is spodumene. Based on Gaines et al analysis (2), spodumene is a mineral that consist of lithium aluminium inosilicate LiAl(SiO3) (p.6). Due to efficiency concerns, its production from minerals has drastically reduced. Eventually, new cost-effective technique, which involves production from salars, has been discovered (1). Nevertheless, producers still consider extraction from mineral deposits, in pursuit of achieving supply diversification and reducing reliability of the external suppliers (4). Besides extracting and processing the ore and raw spodumene must be subjected to a temperature of 1000oC in order to effectively transform alpha to beta and facilitate percolation using sulphuric acid (2). The next process involves recovering of lithium in form of lithium salts. Cathode production The materials that are used in making cathode are manufactured through oxidation of lithium carbonate at a very high temperature. Another chemical used in the process is Lithium hydroxide, which requires special handling during mixing process. Reactions in solid state at a range of temperatures between 600 to 800oC are a fundamental requirement to ensure there is maximum crystallization and that suitable structures are obtained (3). Iriyama et al (7) assert that fossil energy is the most suitable for this process. Structural as well as physical features like packing density and morphology are the key determinants in establishing the appropriateness of the material that should be used in cathode for Lithium-ion cells (1). Anode Production The most commonly used materials in anode production are soft carbon, hard carbon, graphite, and mesocarbon micro-bead (6). Essentially, a temperature of 2700oC is needed for graphitization of synthetic graphite materials (2). The process involves huge consumption of energy, particularly fossil fuels. In the recent past, there has been usage of amorphous carbon layer as a robust way of protecting carbonaceous anode cells against corrosion during cell working periods. According to Casas et al (8) process also involves usage of gas-phase substances like methane and propylene, which need to be exposed to a temperature of 700oC to crack them (1). Other materials that have been widely used to supplant graphite anodes in the recent past are components of Lithium titanate (Li4Ti5O12). Li4Ti5O12 is preferred due to its high-energy supply. To produce Li4Ti5O1, a reaction of TitaniaTiO2 and Li2CO3 is conducted in crystalline structure, at a temperature of 859oC, in the air (1). The process is less energy-intensive compared to the graphite production. Another advantage of Li4Ti5O1 is that it does not react with the electrolyte. Li4Ti5O1 anode also allows faster charge/discharge, insofar as the diffusion lengths are not long. However, for Li4Ti5O1 anode to be effective, according to Oloffson (1), they have to be used with high potential cathodes to minimize the open circuit voltage (OCV) (p.22). The weight of the material may also be disadvantageous in locomotive purposes. Inventory analysis The process of assembling battery The first step of manufacturing Li-ion battery involves processing cathode paste, which is obtained from purchased LiCoO2 powder and binder powder, among other additives, followed by intense pumping to the coating machine (2). During the second stage, coating machines facilitate the spreading of the paste into a thickness of 200-250 m on each side of the aluminium foil. 25-40% of the thickness is lost during drying process (2). To achieve a uniform thickness, coated sheet has to be compressed. In the third stage, production of graphite paste takes place, and then distributed on copper foil to develop anodes. Another important activity in this stage is the trimming off the foil edges. Splicing in of the new foil may also result to loss of some quantity of the material since taped area have to be scraped, which can be redirected to recycling machines (4). The fourth stage involves wounding up of the anode, cathode, and the insulator layers, and then fixing them into rectangular or cylindrical casing. Happening at the fifth stage is the filling of the cells with electrolyte and purchased paste from a chemical supplier (1). During the sixth stage, attachment of safety devices, seals, insulters, and valves, followed by plication of the cells is done. At the seventh stage, fabrication of fully discharged cells is conducted by charging them with a cycler. Cyclers have the capacity to supply high current for electric car batteries. The stage also involves conditioning and testingcharging and discharging them repeatedly to authenticate product quality (6). Energy is involved at this stage and caution is paramount at this stage to outbreak of fires due to large capacity of the batteries that are tested. The main purpose of the eighth stage is to fit the cells with electronic circuit gadgets to control the process of charging and discharging (2). At the final stage, non-homogenous electrode devices, defective cells, and other left overs are dumped to the scrap. Scrap materials may be recycled. Recycling of Li-ion battery Recycling of batteries has become more dynamic due to diversification of feedstock, which includes several types of batteries, some of which are inimical to human health in particular and the environment in general. According to Gaines (2), recycling electronic consumer batteries keeps the companies operational until car batteries are disposed for recycling in huge volumes (p.9). The disposal of automotive batteries makes the recycling process efficient and improves standardization exercise. Income obtained from cobalt recovery stimulates the recycling process (3). However, due to decline in the use of cobalt, other initiatives to make the recycling process lucrative business must be identified. Through the recycling process, several materials can be recovered at different stages of production. For instance, smelting process has the efficacy to retrieve the basic elements and salts. Smelting process occurs at very high temperatures and involves burning of carbon anodes and electrolytes as reductant (2). Cobalt and nickel, which are the valuable metals recovered from the process, are redirected to the refining plant to make them more conducive for any purpose. Other elements that are contained in the slag like lithium are used for additive function. Hydrometallurgical process is the main method that is used to recover lithium from the slag (2). The process of recovering battery grade materials demands a high uniform feed since contamination of the feed with impurities may be detrimental to the product quality. Therefore, component must be separated through effective variety of chemical and physical technique to ensure that all active elements are recovered. Other active mater ials may need to be purification to make them appropriate for reuse in new battery cells. However, the separator cannot be reused since its material cannot be recycled. While many papers have discussed recycling of Lithium-ion batteries, only a few companies, 3 to be exact, have detailed germane information that could be used in current analysis. These processes are analysed below: Umicore Process Umicore is a European battery processing company. It gathers used batteries and dispose them to its processing plant, which is designated in Sweden. Once the materials are collected, they are smelted. The next step is combustion of organic materials in the batteries like carbon electrodes, plastics, and electrolyte solvents. The combustion steers the smelter and carbon is used a reductant for some metals. Recovered elements, nickel and cobalt, are shipped to a refinery plant in Belgium, where CoCl2 is manufactured. After processing CoCl2, it is transported to South Korea to manufacture LiCoO2 for battery cells. Recovery of nickel and cobalt helps makes the process efficient, considering that at least 70% of the energy required for their extraction from the sulphide ores is saved. The production process also prevents emission of Sulphur oxide gase. However, the aluminium and lithium elements from the smelting process flows into the slag, which has low value uses. The subjection of was te gases to extremely high temperatures ensures that they are not released into the environment. According to the company, out of 93% recovered lithium-ion batteries, 69% is metal, 10% is carbon, and 14% is plastic (2). The Toxco Process This method has been commonly used in battery processing since 1993 in Canada to manufacture Lithium-ion batteries for different purposes (3). In 2009, Toxco Company was granted a licence by the US Department of Energy to reprocess Lithium-ion battery cells at plant designated at Ohio (2). Through mechanical and chemical recycling process, products obtained from the process are copper cobalt, fluff, and cobalt filter cake (2). Copper cobalt is used to extract metals like copper, cobalt, nickel, and aluminium. On the other hand, cobalt filter cake is reused to coat appliances. Sodium Chloride was added to the resultant solution in order to precipitate Li2Co3. The mechanical and chemical recycling process ensures that the emission is minimized. One benefit of this process is that it is not energy-intensive. Besides, it is possible to recycle at least 60% of the battery pack materials and 10 percent reused. The fluff consists of 25% of the battery pack: it is first landfilled, and then the plastic can be retrieved when their capacity is high enough to ensure there is efficiency (2). Eco-Bat Process Orengon Company is the developer of this process. The company has partnered with RSR, a recycling company in Texas. Eco-Bat process consumes less energy hence it more efficient. The process involves reusing of electrolyte solvent and salts. Like other recycling processes, reusing the separator is impossible. The metal elements are retrieved and used for recycling. Battery pack casing may also be reused, but the process will depend on the system of configuration in place. The process is a quintessentially possibility of design-for-recycling method. Extraction of electrolyte if facilitated by using supercritical CO2, which carries away the salt and can be reused. The CO2 used in this process can be obtained from burning waste. The leftovers from the structure can be broken down into small fragments to enhance the separation process. This process ensures that active elements are recovered and the new battery is manufactured with minimal treatment. About 80% of the materials used in the process can be recycle. However, the method requires additional separation process to process a mixed feed and to produce high quality final products. Impact analysis: Comparison to total Life-Cycle Energy This section provides a brief evaluation of inventory development based on cradle-to-gate (CTG) life cycle performance of Lithium-ion battery. This involves investigation of alternative fuels as well as advanced automotive technology. Total energy cycle analysis remains the germane approach in this process, which includes plug and the vehicle cycle. The complete energy phases include (a) energy cycle, which is composed of categories, pump-to-wheel (PTW) and wheel-to-pump stages, (b) automotive cycle, which involves battery production. Gaines (2) uses GREET 1.8d.0 and GREET 2.7 to assess the total energy cycle of PHEV20 to establish that there is significant difference between life cycle energy use and the vehicle cycle. At PHEV20, WTP accounts for 23% while PTW accounts for 61%. This reflects the entire environmental score. Large amount of life cycle energy used during battery processing cannot be retrieved during recycling. Nevertheless, materials like copper, aluminium, nickel, and still were able to be recycled. Impact of the Production and recycling process to the environment Moot discussion on environmental impact is corollary to any type of technological development that involves switching from fossil energy. The main challenge with using lithium-ion battery cells is that there is scarcity of lithium. Lithium-ion battery cells are the only material that can be used in manufacturing electric vehicles, with no substitute. The main contentious issue is what will happen in the event that there is scarcity of lithium. There is still no satisfying evidence that the rate at which lithium is processed will be consistent with rate at which electric vehicles will be manufactured. The geographical location is another factor. Currently, lithium deposits are only concentrated in Bolivia and Chile, though other countries like China, Belgium, and Canada have reserves in lower capacity. Manganese, cobalt, and nickel, which are possible elements in the cathode foils, are also scarce. Expansion of electric vehicles may easily lead to their depletion. On the other hand, c opper is very expensive and may not be cost-effective. Improvement analysis The research on how to extract sufficient lithium ores should be intensified. Since there is no actual data that could be used to determine the actual thickness that may result to crash, an investigation should be carried out to fill the gap. The life cycle lengths and their impacts to the environment should further be investigated to establish the best techniques of recycling lithium and reducing emission. Besides, the durability of batteries should be validated with effective experiments, which are faster and efficient. Since cooling process is vital stage in battery pack, the choice of cooling system should be made with a lot of care to reduce the volume of impurities during the process. Conclusion Based on the results obtained from the assessment of life cycle of Li-ion, it is evident that recycling of materials used to recycle lithium significantly reduces the amount of energy used in the production of the material. This is a significant step towards achieving energy efficiency and reducing emissions. However, there is still lack of credible process that can effectively result to voluminous extraction and processing of lithium ions. Bibliography Olofsson, Y.
