摘要： 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.

摘要： A non-aqueous electrolytic solution includes a phosphoric acid diester salt, which can suppress deterioration of charge-discharge characteristics of a power storage element, and can suppress the rise in internal resistance after storage at high temperature. The phosphoric acid diester salt is represented by the following chemical formula (1): in which Mn+ represents a hydrogen ion, an alkali metal ion, an alkali earth metal ion, an aluminum ion, a transition metal ion, or an onium ion, R1 and R2 are different from each other and represent a hydrocarbon group having 1 to 10 carbon atoms, or a hydrocarbon group having 1 to 10 carbon atoms and having at least one of a halogen atom, a heteroatom, and an unsaturated bond, and n represents a valence.

摘要： A nonaqueous electrolytic solution for a secondary battery exhibits excellent cycle characteristics even in high-temperature environments. The solution includes at least one of boric acid esters, acid anhydrides, cyclic carbonates having an unsaturated bond, cyclic carbonates having a halogen atom, cyclic sulfonic acid esters, and amines having an acetoacetyl group. A secondary battery having a positive electrode and a negative electrode makes use of this electrolytic solution.
