METHOD FOR PRODUCING ELECTROCHEMICAL CELLS OF A SOLID-STATE BATTERY

摘要

The method according to the invention for producing at least one electrochemical cell of a solid-state battery, comprising a mixed-conducting anode, a mixed-conducting cathode, and an electrolyte arranged therebetween, is characterized in that firstly a mixed-conducting anode and a mixed-conducting cathode are produced or provided. The surface of at least one of the two electrodes is modified by an additional method step in such a way that, in a layer of the electrode near the surface, the electronic conductivity perpendicular to the cell is reduced to less than 10-8 S/cm. Anode and cathode are then assembled to form a solid-state battery in such a way that the surface-modified layer of at least one electrode is arranged as electrolyte layer between the anode and cathode, and the mixed-conducting electrodes are thereby electronically separated.
