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.
本发明涉及一种非
水电解质溶液,包括(I)选自
氟化线性磺酮和
氟化线性
磺酸酯的化合物中的至少一种,以及(II)电解质盐。这样的非
水电解质溶液具有高氧化抗性,即使产生
氢氟酸时也可以最小化其分解。此外,该溶液在用于二次电池时,不太可能导致电池肿胀和电池性能降低。
