Project partners thyssenkrupp System Engineering GmbH, IAV GmbH, Daimler AG and the Fraunhofer Institute for Ceramic Technologies and Systems IKTS are developing bipolar Li-ion batteries and processes for their fabrication in the EMBATT-goes-FAB project sponsored by the German Federal Ministry for Economic Affairs and Energy.
With the EMBATT battery, the project partners are pursuing a new approach to achieving system-level energy densities of more than 450 Wh/l and hence making the range of electric vehicles suitable for everyday use.
These bipolar Li-ion batteries, like fuel cells, consist of stacked electrodes connected in series. In contrast to conventional Li-ion batteries, these electrodes are, as the name indicates, bipolar. This means that the active materials for the battery cathode and, overleaf, the active materials for the anode are applied to a common electrode carrier.
