Abstract

(DE) Die vorliegende Erfindung betrifft Pulver mit Partikeln aus lithiumionenleitenden Material, das Pulver umfassende Lithiumionenleiter sowie Verfahren zu deren Herstellung. Die Erfindung betrifft auch die Verwendung der erfindungsgemäßen Lithiumionenleiter, insbesondere in Separatoren, Anoden, Kathoden, Batterien und Akkus. Die Erfindung betrifft insbesondere Festkörperionenleiter für den Einsatz in Batterien, insbesondere in Lithiumbatterien und ein Verfahren zu deren Herstellung.

(EN) The invention relates to a powder with particles made of a lithium ion-conducting material, to lithium-ion conductors comprising said powder, and to a method for producing same. The invention also relates to the use of the lithium-ion conductors according to the invention, in particular in separators, anodes, cathodes, batteries, and rechargeable batteries. In particular, the invention relates to solid-state ion conductors for use in batteries, in particular lithium batteries, and to a method for producing same.

(FR) L'invention concerne une poudre comprenant des particules d'un matériau conducteur d'ions lithium, des conducteurs d'ions lithium comportant ladite poudre, et son procédé de production. L'invention concerne également l'utilisation des conducteurs d'ions lithium selon l'invention, en particulier dans des séparateurs, des anodes, des cathodes, des batteries et des batteries rechargeables. En particulier, l'invention concerne des conducteurs d'ions à l'état solide destinés à être utilisés dans des batteries, en particulier des batteries au lithium, et leur procédé de production.
