Abstract:
A phosphodiester salt is added to the electrolytic solution to form a nonaqueous electrolytic solution for a secondary battery. The nonaqueous electrolytic solution has excellent storage characteristics in a temperature load environment. Deterioration of the charge-discharge characteristics of the nonaqueous electrolytic solution and increase in internal resistance of the nonaqueous electrolytic solution are suppressed during storage. A secondary battery having a positive electrode and a negative electrode makes use of this electrolytic solution.
