Title:
POLYMER ELECTROLYTE FOR A LITHIUM METAL POLYMER BATTERY HAVING IMPROVED PERFORMANCE
Document Type and Number:
WIPO Patent Application WO/2020/109711
Kind Code:
A3
Abstract:
The present invention relates to a cross-linked copolymer comprising at least repeating units of poly(alkylene oxide) and at least repeating units of lithium polystyrene-sulfonyl(trifluoromethylsulfonyl)imide (PSTFSILi), the use of such a cross-linked copolymer for preparing a solid polymer electrolyte, a solid polymer electrolyte comprising said cross-linked copolymer, and a battery, for example a lithium metal polymer (LMP) battery, comprising said solid polymer electrolyte.
