Abstract
Provided is a method for producing an electrode for a solid-state battery comprising providing a multilayer solid ceramic electrolyte that comprises at least one dense layer having a total ion conductivity of at least 1 mS/cm at 25° C. and at least one porous layer having continuous and open pores having an average pore diameter between 1 and 50 μm; providing an aqueous infiltration fluid comprising at least one organic additive that can be at least partially converted into carbon; introducing the aqueous infiltration fluid into the at least one porous layer of the multilayer solid ceramic electrolyte; and subjecting the multilayer solid ceramic electrolyte to a thermal treatment in the form of sintering in a reducing atmosphere at temperatures between 400° C. and 900° C., whereby the electrode material is synthesized from the precursor of the electrode material on the surface of the pores in situ.
