Abstract

A solid state laminar electrochemical cell comprising:
an alkali metal anode layer;
a solid ionically conducting electrolyte layer; and a cathode/current collector layer;
wherein said electrolyte layer is interposed between said alkali metal anode layer and said cathode/current collector layer and wherein said cathode/current collector layer comprises an electrically conductive substrate having a plurality of surface voids and a composite cathode composition comprising an intercalation compound, an electrically conductive filler and an ionically conductive electrolyte, said cathode composition being coated on the surface of said substrate facing said electrolyte layer and being maintained in the voids of said surface is disclosed.
