A solid state cell having a solid cathode, a solid electrolyte, and a solid anolyte comprised of at least 50% by volume of ionically conductive materials such as the electrolyte and 50% or less by volume of an active metal. The anolyte is either the cell anode or alternatively the anolyte is an additional structural member within said cell positioned between an anode, comprised of the same active metal, and the solid electrolyte.

Solid state cell with anolyte

An electrochemical cell incorporating cathode materials comprising at least one metal oxide, at least one metal, or mixture of metals or metal oxides incorporated in the matrix of a host metal oxide. The cathode materials of this invention are constructed by the chemical addition, reaction, or otherwise intimate contact of various metal oxides and/or metal elements during thermal treatment in mixed states. The materials thereby produced contain metals and oxides of the groups IB, IIB, IIIB, IVB, VB, VIB, VIIB, and VIII, which includes the noble metals and/or their oxide compounds. The incorporation of the metal oxides, metals or mixtures thereof substantially increases the discharge capacity and the overall performance of the cathode materials.

Metal oxide composite cathode material for high energy density batteries

A solid state cell having a solid cathode, a solid electrolyte, and a solid anolyte comprised of at least 50% by volume of ionicially conductive materials such as the electrolyte and 50% or less by volume of an active metal.
