  • High capacity solid state composite cathode, solid state composite separator, solid-state rechargeable lithium battery and methods of making same
    Patent number: 10333123
    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.
    Type: Grant

  • IMPREGNATED SINTERED SOLID STATE COMPOSITE ELECTRODE, SOLID STATE BATTERY, AND METHODS OF PREPARATION
    Publication number: 20150056520
    Abstract: An impregnated solid state composite cathode is provided. The cathode contains a sintered porous active material, in which pores of the porous material are impregnated with an inorganic ionically conductive amorphous solid electrolyte. A method for producing the impregnated solid state composite cathode involves forming a pellet containing an active intercalation cathode material; sintering the pellet to form a sintered porous cathode pellet; impregnating pores of the sintered porous cathode pellet with a liquid precursor of an inorganic amorphous ionically conductive solid electrolyte; and curing the impregnated pellet to yield the composite cathode.
