German Giants Start R&D Battery Project
STUTTGART, Germany – German industry giants Bosch, BASF, BMW, Daimler, SGL and Wacker Chemie have joined forces in a research project called Alpha-Laion. The project is focused on the development of high-energy lithium-ion batteries for 4-wheeled e-vehicles.
Germany’s Federal Ministry of Economics & Technology is subsidizing the Alpha-Laion project with13 million euro. The six project partners invest 19.5 million euro into what they call: “A national showcase project for e-mobility.”
Technology leadership in cells and batteries
“E-mobility is an important key for climate-friendly and sustainable transformation of mobility. This is the core point of the national e-mobility platform. It compromises the most important industrial and academic partners following the German vision to become leader in the field of e-mobility until 2020”, is noted in a Bosch press release published after the project kick-off meeting. For this transformation it is of fundamental importance: “To establish technology leadership in the field of electrochemical cells and batteries with an integrated production based in Germany,” notes the Bosch press release.
Range and energy storage
Alpha-Laion is to face the current problems of battery technology. Major issues are the operating range of e-vehicles as well as the costs of storing energy. According to the project partners these are key for the breakthrough of e-mobility. Fact is that 4-wheeled e-mobility isn’t meeting its expectations; not only in Germany but worldwide.
New electrochemical system
Major target of Alpha-Laion project is to join forces in the development of high-energy lithium-ion cells; “Based on innovative material for cathodes, anodes, separators and high-voltage stable electrolytes”. The combination of these components will enable; “A complete new electrochemical system for the use of lithium-ion cells. Only the right material combination, a proper cell design and a dedicated to the new materials suited process technology can use the energy storage performance of new lithium-ion cells at its best and reach a high long-term durability,” say the project partners in their press release.
Therefore they hope to realize very soon lithium-ion cells with an energy density of more than 250Wh/kg: “Then we would be able to increase the operating range of 4-wheel e-vehicles significantly to between 250 and 300 kilometers.”
