Lithium-ion battery
Material

Applications are becoming smaller, lighter and more intelligent. The demands on the energy supply in these areas are therefore constantly increasing. VARTA is considered a pioneer with its CoinPower® cell product family. In order to continue to play this role in the future, VARTA is researching new ways to improve its products while at the same time using less scarce and more environmentally friendly resources. The focus is on the further development of the anode, cathode and other cell components.

„Bei CoinPower arbeiten wir erfolgreich daran, mit den neuen Produktgenerationen die Energiedichte stetig weiter zu erhöhen.“

Claus Fischer, Manager Prototyping & Technology Lithium VARTA AG

Research projects

Advanced material solutions for safer and longer-lasting high-capacity cobalt-free batteries for stationary storage applications.

The project focuses on ecologically and economically sensible production and recycling of lithium-ion batteries.

Silicon-Graphene: upscaling the production of high-quality anode materials to the tonne-per-year scale

3D-Si-Elektrode

The project pursues the integration of fabric-based current collectors in VARTA cells, as well as a process for the production of mechanically and structurally stable three-dimensional silicon anodes for Li-Ion batteries. In addition to a significantly higher storage capacity of the cells, the use of copper should be massively reduced and the use of domestic resources of glass and carbon established.
