Abstract
A high capacity solid state composite cathode contains an active cathode material dispersed in an amorphous inorganic ionically conductive metal oxide, such as lithium lanthanum zirconium oxide and/or lithium carbon lanthanum zirconium oxide. A solid state composite separator contains an electronically insulating inorganic powder dispersed in an amorphous, inorganic, ionically conductive metal oxide. Methods for preparing the composite cathode and composite separator are provided.
