Claim 13:
14. A method for preparing a solid-state electrochemical cell having a distributed solid-state electrolyte, the method comprising:
disposing a first solid-state electroactive material layer adjacent a first current collector so as to form a first electrode;
forming a first plurality of apertures within the first electrode, wherein the first plurality of apertures extends continuously through the first solid-state electroactive material layer and the first current collector;
disposing a second solid-state electroactive material layer adjacent a second current collector so as to form a second electrode;
forming a second plurality of apertures within the second electrode, wherein the second plurality of apertures extends continuously through the second solid-state electroactive material layer and the second current collector;
stacking the first and second electrodes so as to form the solid-state electrochemical cell;
impregnating the solid-state electrochemical cell with a solid-state electrolyte precursor solution so as to fill the first and second pluralities of apertures and any other void or pore within the solid-state electrochemical cell with the solid-state electrolyte precursor solution; and
heating the solid-state electrolyte precursor solution so as to solidify the solid-state electrolyte precursor solution and to form the distributed solid-state electrolyte.
