Non-aqueous electrolyte cell with a solvent including a S-O bond

A nonaqueous electrolytic solution for a nonaqueous electrolytic solution cell:

• wherein the nonaqueous electrolytic solution consists of solute and organic solvent and the nonaqueous electrolytic solution contains at least one organic solvent represented by the formula (1):
• R1−A−R2 (1)
• in which,
• R1 and R2 independently represent an alkyl group which may be substituted with an aryl group or halogen atom;
• an aryl group which may be substituted with an alkyl group or halogen atom;
• or may be taken together to form, together with -A-, a cyclic structure which may contain an unsaturated bond, where “A” is represented by a formula selected from the group consisting of:
• wherein the nonaqueous electrolytic solution cell comprises a negative electrode containing lithium as an active material, a positive electrode, a separator and an outer can,
• wherein a current collector for the positive electrode is made of valve metal or an alloy thereof, and
• wherein a portion of the outer can contacting the electrolytic solution at the side of the positive electrode is made of valve metal or an alloy thereof.
