A method for preparing a lithium ion solid-state accumulator comprising an anode, a cathode, and a solid-state electrolyte includes pressing and sintering pre-calcined electrolyte powder to an electrolyte layer. The pre-calcined electrolyte powder comprises at least one phosphate compound, at least one silicide compound, or at least one phosphorus sulfide. The method further includes applying, on both sides of the electrolyte layer, one electrode each. Prior to the application of the at least one electrode layer on a surface of the sintered electrolyte layer, first, at least one intermediate layer, and, then, on this intermediate layer, the electrode layer is applied. The at least one intermediate layer is a layer of electrolyte and anode material and/or a layer of electrolyte and cathode material.
