Title:
ACTIVE-MATERIAL ELECTROLYTE COMPOSITE, PROCESS FOR PRODUCING SAME, AND ALL-SOLID-STATE LITHIUM-SULFUR SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2012/014852
Kind Code:
A1
Abstract:
Disclosed is an active-material electrolyte composite prepared by: providing a gelled electrolyte on an electrode, the electrode including a charge collector and an electrode material provided thereon, the electrode material being prepared by mixing an active material, an electroconductive aid, and a binder at a predetermined mixing ratio and containing elemental sulfur or a lithium-containing sulfide as a positive-electrode active material, the gelled electrolyte containing an ether-based organic solvent and comprising a mixture of a lithium-ion-conductive electrolytic solution and a swellable layered clay mineral; and subjecting the electrode to a vibration having an intensity that will liquefy the gelled electrolyte. Also disclosed is an all-solid-state lithium-sulfur secondary battery produced by using said composite.
