Abstract

A galvanic element includes at least one lithium-intercalating and at least one lithium-deintercalating electrode. A positive electrode and a negative electrode are separated by a polyimide-based separator that has a labyrinth porosity. The polyimide-based separator is configured at least on one side with a porous, ceramically-based coating that comprises a binder and ceramic particles.
