Tags: starting a new company that will attempt to resolve major obstacle facing electric vehicles today -. the cost of their battery Tags new company, called 24m, has been turned by advanced battery company A123 Systems. It will develop a new type of battery based on a study conducted by Yet-Ming Chiang, a professor of materials science at MIT and founder of A123 Systems. He said that the battery design has the potential to reduce costs by 85 percent.
Tags only the battery pack in a lot of electric cars may cost more, 000. Cutting this figure may make electric vehicles competitive with gasoline-fueled cars. Tags: new company has raised million in a joint-capital funds, and about the Advanced Research Projects Agency million-Energy (ARPA-E), which will fund joint venture of MIT and Rutgers University. A123 Systems will work closely with the new company, and owns shares in it. The name stands for “24 molar,” referring to Chiang concentrations cryptically calls “technically relevant” to Chiang kompanisë.Tags not say much about the details of a new battery – such as what is important is the Posted by. But he said he uses “semisolid” energy storage (instead of solid electrode materials used in batteries today), and because it combines the best features of conventional batteries, fuel cells and batteries, called a course, avoiding some of the weaknesses this technology. A Tags: advantages of lithium-ion batteries – the type used in laptop computers, and that will be used in a new wave of electric vehicles begins at the end of the year – is that the electrode materials can save a lot of energy. But the packaging is required to address the energy to take a lot of space and add cost and weight. “In a typical rechargeable batteries such as Laptop IBM ThinkPad T40 Battery IBM 92P1101 battery and IBM, it is only half the actual energy storage. Next is the material support,” said Chiang. “This is a problem I have thought for years – how do you improve the efficiency of the design?” Tags reduce the amount of material is not easy. To extract a useful amount of electrical current from the electrode material, the material shall be spread a thin layer on a piece of foil, which takes much of the total in the cell. Tags: fuel cells and flow batteries do not have this problem. Energy-storage materials – fuels such as hydrogen or liquid electrolyte, respectively – can flow through the membrane, which makes it easier to get energy from
Problems Tags: a. fuel cells is that it can not be met by using an electric current – you need to refill the fuel tank. This is OK if the fuel is widely available, but now the hydrogen can be hard to come by. Flow requires a lot of battery electrolyte, because their energy density is low. “It’s like managing a large swimming pool filled with corrosive liquid,” said Chiang. As a result, the flow is not practical for a car battery.
Tags: As fuel cells, new battery can store more energy, without a large amount of interesting material to support it, said Chiang. However, it is sure rechargeability and energy density of lithium battery electrode materials. The result is that the battery can store relatively large amount of energy at low cost. But he deliberately vague about the mechanisms involved, only saying “the latest version of the device will look very different from the two conventional batteries and flow batteries.” Chiang Tags said the new design can work with a variety of battery chemistries. So far, he has developed a test-of-concept device – which is necessary for the ARPA-grants. But, he said, “there are a lot of work to be done.” He has set a target of five years to get them in the field.
