Title
(EN) LITHIUM LANTHANUM ZIRCONIUM OXIDE (LLZO) POWDER
(FR) POUDRE D'OXYDE DE LITHIUM, DE LANTHANE ET DE ZIRCONIUM (LLZO)
Abstract
(EN)
Disclosed herein are embodiments of doped and undoped spherical or spheroidal lithium lanthanum zirconium oxide (LLZO) powder products, and methods of production using microwave plasma processing, which can be incorporated into solid state lithium ion batteries. Advantageously, embodiments of the disclosed LLZO powder display a high quality, high purity stoichiometry, small particle size, narrow size distribution, spherical morphology, and customizable crystalline structure.
(FR)
L'invention concerne des modes de réalisation de produits en poudre d'oxyde de lithium, de lanthane et de zirconium (LLZO) sphériques ou sphéroïdaux dopés et non dopés, et des procédés de production utilisant un traitement par plasma micro-ondes, qui peuvent être incorporés dans des batteries lithium-ion à l'état solide. De manière avantageuse, des modes de réalisation de la poudre de LLZO selon l'invention présentent une une stœchiométrie de haute qualité, de pureté élevée, une petite taille de particule, une distribution de taille étroite, une morphologie sphérique et une structure cristalline personnalisable.
