Title:
ALL-SOLID-STATE LITHIUM SECONDARY BATTERY AND PRODUCTION METHOD FOR ALL-SOLID-STATE LITHIUM SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/075420
Kind Code:
A1
Abstract:
An all-solid-state lithium secondary battery (1) comprising: an oxide solid electrolyte layer (11) including oxide solid electrolyte particles (11a) having lithium ion conductivity; a positive electrode active material layer (13) arranged on one surface side of the oxide solid electrolyte layer (11); a negative electrode active material layer (16) arranged on the other surface side of the oxide solid electrolyte layer (11); and a solid electrolyte dispersion polymer layer arranged between the oxide solid electrolyte layer (11) and at least either the positive electrode active material layer (13) or the negative electrode active material layer (16) and having oxide solid electrolyte particles dispersed in a lithium ion conductive polymer material that has lithium ion conductivity. The positive electrode active material layer (13), the negative electrode active material layer (16), the solid electrolyte dispersion polymer layer, and the oxide solid electrolyte layer (11) are integrated.
