Title
(EN) IMPREGNATED SINTERED SOLID STATE COMPOSITE ELECTRODE, SOLID STATE BATTERY, AND METHODS OF PREPARATION
(FR) ÉLECTRODE COMPOSITE IMPRÉGNÉE, FRITTÉE ET À SEMI-CONDUCTEURS, BATTERIE À SEMI-CONDUCTEURS ET PROCÉDÉS DE PRÉPARATION
Abstract
(EN) 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.
(FR) L'invention se rapporte à une cathode composite imprégnée à semi-conducteurs. La cathode contient un matériau actif poreux fritté, dans lequel les pores du matériau poreux sont imprégnés d'un électrolyte solide amorphe inorganique et ioniquement conducteur. Un procédé de production de la cathode composite imprégnée à semi-conducteurs consiste à former une granule contenant un matériau de cathode d'intercalation actif; à fritter la granule pour former une granule de cathode poreuse frittée; à imprégner les pores de la granule de cathode poreuse frittée d'un précurseur liquide d'un électrolyte solide amorphe inorganique et ioniquement conducteur; et à durcir la granule imprégnée pour produire la cathode composite.
