Claim 0:
1. A method for preparing a solid-state electrochemical cell having one or more solid-state electrodes and a distributed solid-state electrolyte, the method comprising:
preparing the one or more solid-state electrodes by disposing a solid-state electroactive material layer adjacent to a current collector, the solid-state electroactive material layer comprising a plurality solid-state electroactive particles;
punching a plurality of apertures into the one or more solid-state electrodes, the plurality of apertures extending continuously through the solid-state electroactive material layer and the current collector;
impregnating the one or more solid-state electrodes with a solid-state electrolyte precursor solution so as to fill the plurality of apertures and any other void or pores within the one or more electrodes with the solid-state electrolyte precursor solution; and
heating the one or more electrodes so as to solidify the solid-state electrolyte precursor solution and to form the distributed solid-state electrolyte.
