Researchers at the Centre for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW have developed advanced lithium-ion batteries for electric vehicles and solar power storage systems.

The new lithium-ion batteries after 10,000 complete charging and discharging cycles with a complete charge and discharge cycle per hour will still have around 85% of the initial capacity.

Commenting on the development, Accumulator Material Research Department Ulm head Margret Wohlfahrt-Mehrens said batteries employing lithium-ion technology should have the capacity to work in cars for around 10 years without the battery capacity dropping to less than 80% of the rated value.

This development has been funded by the German Federal Ministry of Education and Research, and the German Federal Ministry of Economics and Technology.

Meanwhile, the researchers and engineers at ZSW are planning to further develop electrodes for large prismatic lithium cells.
