PERFLUORINATED PHOSPHATE CROSSLINKER FOR GEL POLYMER ELECTROLYTE, GEL POLYMER ELECTROLYTE PREPARED FROM THE SAME AND ELECTROCHEMICAL DEVICE COMPRISING THE ELECTOLYTE

摘要

PURPOSE: A perfluorinated phosphate acrylate cross-linking agent for gel polymer electrolyte of a specific structure is provided to ensure electrochemical stability and thermal stability. CONSTITUTION: A perfluorinated phosphate acrylate cross-linking agent for gel polymer electrolyte is denoted by chemical formula 1. A composition for gel polymer electrolyte contains electrolyte solvent, lithium salt, and gel polymer electrolyte monomer and further contains perfluorinated phosphate acrylate cross-linking agent. The electrolyte solvent is circular carbonate, linear carbonate, lactone, ether, ester, sulfoxide, acetonitrile, lactame, ketone or halogen derivative thereof. The gel polymer electrolyte is formed by polymerizing the composition for gel polymer electrolyte. An electrochemical device contains anode, cathode and gel polymer electrolyte.
