Abstract: The invention relates to a cathode (A) for lithium ion accumulators, comprising (a1) at least one current collector, (a2) at least one layer comprising at least one cathode-active material which stores/releases lithium ions, at least part of layer (a2) having been compacted and/or the side of layer (a2) facing the anode having at least one layer (a3) which comprises at least one solid electrolyte which conducts lithium ions, said solid electrolyte being selected from the group consisting of inorganic solid electrolytes and mixtures thereof and being insoluble in the electrolyte system (B) used in the lithium ion accumulator, to lithium ion accumulators comprising the cathode (A) and to a process for producing the cathode (A).
