Scientists at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) have developed top-class lithium-ion batteries for electric cars with an unprecedented 27-year lifetime.
The lithium-ion batteries developed in the ZSW are among the best in their class in terms of technological development.
The high performance cells exceed the international state-of-the-art technology in terms of cycle stability, an important key value for working life duration. Over 10,000 full cycles have been achieved so far, while maintaining more than 85% of the initial capacity.
In terms of other characteristic values such as power density, the batteries attain a level which is comparable to the Asian products which have led the market until now. The active materials for the batteries exclusively originate from German companies.
ZSW designed the cells, developed the manufacturing process and produced a small sample series in the 18650 format.
The technology has also created the basis for manufacturing large-size pouch and prismatic cells. The Lithium-ion batteries are intended for use in electric vehicles and as solar power storage systems.
