Production technology for hybrid solid-state batteries with lithium metal anode – ProHybrid

The aim of the project „Production technology for hybrid solid-state batteries with lithium metal anode" (ProHybrid) is the production of solid-state batteries. In addition to that, scalable production processes are to be developed.

The unique feature of the ProHybrid project approach is the simultaneous use of two different solid electrolytes. An oxide ceramic solid electrolyte is to be used as the underlying support structure of a mixed cathode. A mixture of active material and a polymer electrolyte will then be introduced into this structure. This hybrid approach makes it possible to combine the good ionic conductivity and stability of the ceramic with the good contact surface of a polymer. For the separator, concepts made of ceramic or polymer electrolyte are to be tested. Metallic lithium is planned as the anode material.
