Non-flammable electrolyte composition including carbonate-terminated perfluoropolymer and phosphate-terminated or phosphonate-terminated perfluoropolymer and battery using same

摘要

Provided herein are functionally substituted fluoropolymers suitable for use in liquid and solid non-flammable electrolyte compositions. The functionally substituted fluoropolymers include perfluoropolyethers (PFPEs) having high ionic conductivity. Also provided are non-flammable electrolyte compositions including functionally substituted PFPEs and alkali-metal ion batteries including the non-flammable electrolyte compositions.
