Abstract
The present invention directs to a non-aqueous electrolyte solution, including (I) at least one compound selected from the group consisting of fluorinated linear sulfones and fluorinated linear sulfonic acid esters, and (II) an electrolyte salt. Such a non-aqueous electrolyte solution has high oxidation resistance, minimizes its decomposition even when hydrofluoric acid is produced. Also, the solution is less likely to cause, in the case of being used for a secondary cell, swelling of the cell and lowering of the battery performance.
