Aluminum based battery systems

Fraunhofer THM/IISB develops and analyses sustainable battery systems on the basis of an improved life cycle assessment and the availability of raw materials compared to established battery systems.

In particular, the rechargeable aluminum based battery is a sustainable alternative to lithium ion batteries (LIB). The theoretical volumetric capacity of an aIuminum metal anode is four times higher than that of metallic Li. In addition, the costs are very attractive compared to LIB. Despite the early stage of development, we had reached energy densities for AIB which is comparable to NiCd batteries.

New cathode materials, slurries and electrolytes are produced in close cooperation with partners from academic research and industry. These materials are assembled into battery test cells, e.g. button cells, and are characterized with respect to their electrochemical behaviour and their structural and morphological properties.
