First claim
Opening claim text (preview).
1 . An electrolyte solution comprising: tris(trimethylsilyl) phosphite; and at least one fluorinated saturated cyclic carbonate (1) selected from the group consisting of a compound (1-a) and a compound (1-b), the compound (1-a) being represented by the following formula: the compound (1-b) being represented by the following formula: 2 . The electrolyte solution according to claim 1 , further comprising a solvent. 3 . The electrolyte solution according to claim 2 , wherein the solvent contains at least one selected from the group consisting of a non-fluorinated saturated cyclic carbonate, a fluorinated saturated cyclic carbonate other than the fluorinated saturated cyclic carbonate (1), a non-fluorinated acyclic carbonate, a fluorinated acyclic carbonate, a non-fluorinated acyclic ester, and a fluorinated acyclic ester. 4 . The electrolyte solution according to claim 2 , wherein the tris(trimethylsilyl) phosphite is present in an amount of 0.001 to 10% by mass relative to the solvent. 5 . The electrolyte solution according to claim 2 , wherein the fluorinated saturated cyclic carbonate (1) is present in an amount of 0.001 to 10% by mass relative to the solvent. 6 .
