Abstract
An electrolytic solution for a nonaqueous electrolyte battery according to the present invention includes: (I) at least one kind of silane compound represented by the following general formula (1); (II) at least one kind selected from the group consisting of a cyclic sulfonic acid compound and a cyclic sulfuric ester compound; (III) a nonaqueous organic solvent; and (IV) a solute. The nonaqueous electrolyte battery with this electrolytic solution achieves a good balance between improvement of high-temperature storage characteristics under high-temperature conditions of 70° C. or higher and reduction of gas generation during high-temperature storage.Si(R)(R)  (1) In the general formula (1), Ris each independently a carbon-carbon unsaturated bond-containing group; Ris each independently selected from a fluorine group and a C-Clinear or C-Cbranched alkyl group which may have a fluorine atom and/or an oxygen atom; and x is an integer of 2 to 4.
