ABSTRACT:
A non-aqueous electrolyte solution having a large capacity, exhibits high storage characteristics and cycle characteristics, and is capable if inhibiting gas generation. The non-aqueous electrolyte solution contains a lithium salt and a non-aqueous solvent, and a cyclic carbonate compound having an unsaturated bond in a concentration of 0.01 weight % or higher and 8 weight % or lower; and a compound expressed by a formula (IIb) in a concentration of 0.01 weight % or higher and 5 weight % or lower:wherein Z5represents an integer of 2 or larger, X5represents a linkage group comprising one or more atoms selected from the group consisting of a carbon atom, a hydrogen atom, a fluorine atom and an oxygen atom, and the fluoro sulfonyl group is bound to a carbon atom of the linkage group.
