BATTERY ELECTROLYTE SOLUTION CONTAINING CERTAIN ESTER-BASED SOLVENTS, AND BATTERIES CONTAINING SUCH AN ELELCTROLYTE SOLUTION

摘要

Battery electrolyte solutions contain certain ester solvents, a lithium salt and vinylene carbonate, vinyl ethylene carbonate or fluoroethylene carbonate. Batteries containing these solvents have excellent specific discharge capacities and reduced weight compared to batteries in which the electrolyte is based on ethylene carbonate.
