Title
(EN) DENSE ELECTRODE FOR SOLID STATE BATTERY
(FR) ÉLECTRODE DENSE DE PILE À ÉLECTROLYTE SOLIDE
Abstract
(EN) A method for producing a cathode membrane for use in a lithium ion battery using milling and sintering. The cathode membrane is comparatively dense. The cathode membrane can be formed by a composition of active materials and inorganic lithium ion conductors. Conductive additives can be included in the cathode composition. A conducting coating can be applied to a surface of the cathode membrane.
(FR) L'invention concerne un procédé de production, par broyage et frittage, d'une membrane de cathode destinée à être utilisée dans une pile au lithium-ion. La membrane de cathode est comparativement dense. La membrane de cathode peut être formée par une composition de matériaux actifs et de conducteurs d'ions lithium inorganiques. Certains additifs conducteurs peuvent faire partie de la composition de cathode. Un revêtement conducteur peut être appliqué à une surface de la membrane de cathode.
