ELECTROLYTE COMPOSITION AND CELL

摘要

An electrolyte composition characterized by comprising: (1) a polymer having an ether bond as an optional ingredient; (2) an additive comprising an ether compound having ethylene oxide units as an optional ingredient; (3) a lithium salt compound; and (4) a cyclic carbonate having an unsaturated group. The electrolyte composition is excellent in processability, moldability, mechanical strength, flexibility, heat resistance, etc. and has significantly improved electrochemical properties with respect to action on lithium metal.
