  • Electrolyte for nanaqueous battery, method for producing the same, and electrolytic solution for nonaqueous battery
    Publication number: 20040137324
    Abstract: An electrolyte for a nonaqueous battery according to the present invention consists essentially of magnesium bistrifluoromethanesulfonimide. An electrolytic solution for a nonaqueous battery according to the present invention includes the magnesium bistrifluoromethanesulfonimide, and an organic solvent such as a cyclic carbonate, a chain carbonate, a cyclic ether and a chain ether or an ordinary temperature molten salt having a melting point of 60° C. or less in which the magnesium bistrifluoromethanesulfonimide is dissolved.
