SOLID ELECTROLYTE FOR LITHIUM BATTERY, COMPRISING AT LEAST ONE ZONE OF LITHIUM-CONTAINING GLASS CERAMIC MATERIAL AND METHOD OF PRODUCTION.

摘要

At least one zone made of lithium-containing glass ceramic material, in a solid electrolyte for lithium battery, is formed from a lithium-containing ceramic material, advantageously in the form of a layer such as a thin film. It is obtained by fusing at least one part of the lithium-containing ceramic material, followed by a recrystallization heat treatment. The fusion is obtained through a laser beam irradiation operation, thereby making it possible to carry out the fabrication of the solid electrolyte directly on a multilayer stack comprising certain active components of the lithium battery.
