Energy Materials

We analyze rechargeable aluminum-ion battery systems as future long-term alternative of lithium-ion batteries. Therefore, we develop new cathode materials and electrolytes. The materials are assembled into battery test cells and characterized with respect to their electrochemical behavior.

Furthermore, we develop technologies to recycle silicon from sawing waste and to reuse the recycled silicon for thermoelectric generators, as anode material for lithium batteries and for precursors for 3D printing of lightweight AlSi alloys.
