Document Type and Number:
WIPO Patent Application WO/2017/128983
Kind Code:
A1
Abstract:
Provided in the present invention are a positive electrode composite material for an all-solid-state lithium ion battery, and a preparation method and an application therefor, the positive electrode positive material having a core-shell structure, the core comprising positive electrode active material, and the shell comprising a polymer electrolyte and a sulphide solid-state electrolyte. The positive electrode composite material for an all-solid-state lithium ion battery provided in the present invention has a simple preparation procedure, and can effectively improve the interface problem between the positive electrode and inorganic solid electrolyte of a lithium ion battery; an all-solid-state lithium ion battery prepared using said material has good recycling service life and better safety performance.
