PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution and a secondary battery which enable the increase in incombustibility while suppressing the worsening of a battery performance, and to provide a nonaqueous electrolytic solution which is fit for a battery arranged by use of a positive electrode material including Ni and/or Mn, and usable until reaching a high potential, and delivers a superior performance as described above, and a secondary battery arranged by use of such a nonaqueous electrolytic solution.SOLUTION: A nonaqueous electrolytic solution comprises: a nonaqueous solvent; an electrolyte; and a combustion inhibitor. The combustion inhibitor contains a phosphazene compound. The nonaqueous electrolytic solution satisfies particular requirements defined by the boiling point of the combustion inhibitor, the boiling point of the solvent, etc. |
