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. |

1. A non-flammable electrolyte composition comprising:
an electrolyte liquid comprising a carbonate-terminated fluoropolymer, a phosphate-terminated or phosphonate-terminated fluoropolymer, and one or more additives, wherein the weight ratio of the carbonate-terminated fluoropolymer to the phosphate-terminated or phosphonate-terminated fluoropolymer is at least 1.6:1 and together the carbonate-terminated fluoropolymer and phosphate-terminated or phosphonate-terminated fluoropolymer constitute at least 50% by weight of the electrolyte liquid, wherein the carbonate-terminated fluoropolymer includes a terminal perfluoropolyether group that terminates in CF3(CF2)n′wherein n′ is 0 or an integer greater or equal to 1, and wherein the phosphate-terminated or phosphonate-terminated fluoropolymer includes a terminal perfluoropolyether group that terminates in CF3(CF2)n″, wherein n″ is 0 or an integer greater or equal to 1. |
