Title:
MULTILAYER BODY CONTAINING ACTIVE MATERIAL LAYER AND SOLID ELECTROLYTE LAYER, AND ALL-SOLID LITHIUM SECONDARY BATTERY USING SAME
Document Type and Number:
WIPO Patent Application WO/2006/064774
Kind Code:
A1
Abstract:
Disclosed is a multilayer body comprising an active material layer and a solid electrolyte layer which is bonded to the active material layer by sintering. The active material layer contains a crystalline first substance capable of discharging and adsorbing lithium ions, and the solid electrolyte layer contains a crystalline second substance having lithium ion conductivity. Incidentally, when this multilayer body is analyzed by an X-ray diffraction method, there is detected no component other than the constituents of the active material layer and the constituents of the solid electrolyte layer. Also disclosed is an all-solid lithium secondary battery comprising such a multilayer body and a negative electrode active material layer.
