FUNCTIONALIZED PHOSPHORUS CONTAINING FLUOROPOLYMERS AND ELECTROLYTE COMPOSITIONS

摘要

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