Scientists at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW) have developed top-class lithium-ion batteries. In terms of the cycle stability – an important parameter for the lifetime – the high-performance cells now exceed the current international state of technology: more than 10,000 full cycles have been achieved so far. With other values, such as the power density, the batteries are equivalent to those produced by the leading Asian manufacturers. The active materials for the batteries exclusively originate from German companies. ZSW has designed the cells, developed the manufacturing process and produced a small sample series in the 18650 format. The technology has created the basis for manufacturing large size pouch cells and large size prismatic cells. Lithium-ion batteries are intended for use in electric vehicles and as solar power storage systems.
