For day-to-day running, motor vehicles with an electric drive concept require reliable and high-capacity energy storage as a key precondition.

For the battery stacks of electrically driven vehicles, today predominantly LiCoO2 cells are used, the power density of which can reach 190 Wh/kg. Recent developments have eliminated one weak point of these batteries, the risk of explosion and severe damage, by using a solid electrolyte such as Kx[MnGe4Se10] with x = 1-4 as an ionic conductor.

According to the state of the art, batteries with oxide ceramic separator made of ß-Al2O3 ceramic reach power densities up to 160 Wh/kg. Although they are designed primarily for stationary operation, they have been used in relatively small commercial vehicles for more than 10 years as reliable and operationally safe energy storage.
