Title: VINYLIDENE FLUORIDE COPOLYMER FOR GEL-FORM SOLID ELECTROLYTE FORMATION, SOLID ELECTROLYTE, AND BATTERY
Abstract:
A solid polymer electrolyte having improved ionic conductivity, improved adhesion to a collector base, and greatly improved heat resistance is formed from a crosslinked vinylidene fluoride copolymer comprising 50 to 97 mol % of vinylidene fluoride monomer units and 0.1 to 5 mol % of units derived from either a monoester of an unsaturated dibasic acid or an epoxy vinyl monomer. It is useful for improving the properties of non-water-base batteries such as lithium ion batteries.
