While Lithium based batteries have allowed electronic products to become more portable, current applications of lithium based batteries are starting to show the limitations of the current technology. These limitations include aspects such as energy density, charge rate, and the usable lifetime of the battery. Furthermore, over the past decade safety concerns of lithium ion batteries have become more and more apparent in both industrial and consumer uses of lithium based batteries.
The push towards electric cars in recent years has resulted in an exponential growth in the demand for lithium-ion batteries that have a large capacity since a fully electric car is limited by the max capacity of its battery. According to battery university,

If ignited, these gases can cause enclosed areas to overpressurize, and if unmitigated, this overpressure can result in an explosion and severe damage to the battery and surrounding equipment or people.(9)” The risk of this happening increases as battery size increases since if one cell fails in a way that emits a large amount of heat, it can heat up the surrounding cells to heat up and subsequently fail. Jason Hughes conducted a teardown of the lithium ion battery in the Tesla Model S P100D and discovered that the 100 kWh battery contained 8,256 cells, while tesla does have safety measures in place to prevent the cells from being damaged, a single manufacturing defect in any of the 8,256 cells could cause a cascading thermal runaway event.
An alternative solution to the limited range of electric vehicles is to offer a large number of publicly available charging stations for electric vehicles. These charging stations boast a charging rate of 170 miles in 30 minutes, which is much faster than the 4 hours and 56 minutes that a standard wall connector would take to charge the car to this range as calculated on Tesla’s website(12). The problem with this solution is that while lithium based batteries can be charged quickly through processes such as tesla 's supercharging, the longevity of the battery can be greatly damaged by doing so. Fast charging a lithium based battery is most effective then the battery is almost depleted and the voltage per cell
The graph shown above compares the different classes of lithium ion batteries that are available today in terms of their specific capacities. The Nickel Cobalt Aluminium combination is by far the most productive lithium ion battery till date. The Lithium Cobalt Oxide battery and the Nickel Manganese Cobalt battery also have a decent amount of energy capacity. The graph also seems to reveal that research on batteries have come a long way from the conventional lead acid batteries.
Kirsch’s main argument in the article is that there are no better storage batteries for the electric vehicle despite smaller technological changes or improvements that have relatively enhanced the capability of these vehicles. The expectations for better storage batteries were not realized though the electric vehicle was
Ronnie Steele’s case analysis creates strong argument for both biofuels and lithium polymer batteries to be used in order to increase engine performance. For each he presented pro’s and con’s that allowed the reader to develop an informed opinion.
In the market today, there are some factors that can pose a problem to all the market players’ including the Model S. The idea of fully electric vehicles is still a new idea in the eyes of consumers. The major concern for the market would be the location and proximity of charging stations for the vehicles. Major cities are starting to increase the amounts that are located within them, but are still not as readily
Some users are discouraged by the fact that it takes almost five hours to completely charge the car using a home electric plug, while putting gas on it would only need a few minutes of their time. Tesla needs to invest in research to offer a faster charge time so that the consumers will not see this as a disadvantage.
Lithium-ion batteries are becoming more common in portable electronic devices due to their high-energy density, lack of memory effect, and high charge and discharge rate capabilities. Research and development work is ongoing to improve safety and increase capacity, charge/discharge rate, and lifetime. Demand for electric vehicle batteries is currently small, but it is expected to grow very quickly. China, Japan, South Korea, France, and the United States are the major lithium-ion battery manufacturers for hybrid and electric vehicle applications.
Have you ever wondered what to do with those rechargeable batteries you have lying around? You want to throw them away but being a responsible person you worry about their hazardous qualities. So you hang on to them for a while and eventually throw them out.
The battery of the electric car stores chemical energy and converts the energy to electricity. The chemistry of the electric car is found mainly in the battery. In the battery there is a chemical reaction in cells which then produces a voltage. These batteries usually have 200 to 400 small cells. The cells are combined to create a powerful battery. The risk is that if one cell overcharge it causes a thermal reaction. The development electronic controls for this risk are in process but are expensive. Khalil Amine and Zonghai Chen of the Argonne National Laboratory discovered a molecule base of boron and fluorine added to each cell controls the charging of the battery cells. The molecule is said to be less costly and more reliable than the electric control. (MANDEL, 2009)

After the success of electric cars in the West, manufacturers from around the globe are entering into this business. With more players in the market, the competition is expected to be intense.
The Back Bay battery simulation presents the managers with a dilemma of choosing between an established, profitable product and a new innovative opportunity. The decision has to be taken through investments in R&D and also make sales forecast for the coming year. Even though, the main aim of this exercise was to generate maximum profit but it actually is a way of analysing complex information and making decisions with the help of news flash updates about current trends amidst unstable market conditions. During the duration of eight years, a balance has to be established between a profitable stable product and an innovative product while keeping in mind the objective of generating maximum cumulative profit.
Electrical vehicles technology has been present for a while and is a proven technology that need only reshaping to meet the global need. Though, in the past, the technology had failed to compete with the internal combustion engine due to initial cost, the technology has done well in the past few years. Electric vehicle ability to reduce the emission of greenhouse gases like carbon and carbon dioxide and the advantages it enjoys such as low maintenance and running cost can enhance it market competitiveness. However, as experts try to make its charging system more efficient and its ability to store charge more long lasting, the global need continue to rise. The research proposal, therefore, aim at addressing an issue like government involvement can enhance improved use of EV, development of better EV batteries, energy management system and fast charging can help enhance the use of Electrical Vehicles and how electric vehicle drive train and the battery can be redesigned to make it affordable.
The infrastructure around electric cars doesn't exist. Tesla Motors are doing their best to change this by building Superchargers, which are like gas stations but for electric vehicles only. It will be free to charge your Tesla Motors car at these stations.
Cars are used by many people all over the world to get them from place to place. Most of these cars are powered by gasoline, some are powered by diesel, and some newly cars are powered electrically. Many people believe that electric cars can be the future of the car industry, but will most other car companies hurt from this? Electric cars use an electric motor to power the car instead of an engine, the owner of an electric car recharges the battery inside the car to power the motor. According to Tesla Motors, an electric car company, “Tesla possesses a high powered wall connector, which completely recharges the car in under 4 hours, and at max power, the high powered wall connector charges at a speed of 56 miles range per hour”(Tesla Motors “Tesla Vehicles Provide Attractive Environmental Benefits” 6). While electric cars do not have as much range as gas-powered cars, no emissions are made from the electric battery, which in result ends up benefiting to the environment.
