Better batteries for electric cars

 “The breakthrough with electric cars is a long time coming – not least on account of their key component, the battery. Lithium-ion batteries are still too expensive and their range too limited. New materials should pave the way for better batteries. Simulation software from researchers is helping speed up the development process. … Consumers are not willing to compromise one iota when it comes to range. Around one third of drivers are looking for a range of at least 500 kilometers. And here is the crux: A lack of charging stations and limited battery life have so far prevented compact electric vehicles from going mainstream. The lithium-ion batteries used by most automakers are simply too heavy, too expensive and go flat too quickly. New materials should improve the performance, service life and safety of the energy storage device, yet the development of these kinds of materials is time-consuming and costly. In the Fraunhofer System Research for Electromobility (FSEM) project, researchers from the Fraunhofer Institute for Industrial Mathematics ITWM in Kaiserslautern are developing software to simulate lithium-ion batteries, which should in turn speed up this process and make it more efficient. The new software is dubbed BEST, short for Battery and Electrochemistry Simulation Tool.” Read more at http://www.fraunhofer.de/en/press/research-news/2010-2011/15/better-batteries-for-electric-cars.jsp
