Document Type and Number:
WIPO Patent Application WO/2023/190625
Kind Code:
A1
Abstract:
Provided are a modified sulfide solid electrolyte and a production method for same as well as an electrode combined material and a lithium-ion battery using same. This modified sulfide solid electrolyte is excellent in application adequacy when applied as a paste and is capable of exhibiting excellent battery performance in terms of efficiency, even when the sulfide solid electrolyte has a large specific surface area. The modified sulfide solid electrolyte has a BET specific surface area of 10m2/g or more and includes: a sulfide solid electrolyte including a lithium atom, a sulfur atom, a phosphorus atom, and a halogen atom; and a compound including two or more hetero rings each having a carbon atom and an oxygen atom.
