Abstract:
An electrolyte for a lithium ion secondary battery includes a non-aqueous organic solvent; lithium salt; and difluoro oxalato borate and fluoro ethylene carbonate (FEC). The capacity retention property and durability of a lithium ion secondary battery including the electrolyte is excellent even when the battery is left at a high temperature.
