SUMMARY OF THE INVENTION An object of the present invention is to provide a nonaqueous electrolyte secondary battery having improved recovery characteristics before and after high temperature standing. [Solution] A nonaqueous electrolyte secondary battery having a positive electrode, a negative electrode prepared by using a negative electrode paste containing a silicon-based negative electrode active material, and a non-aqueous electrolyte, and an ionic compound represented by the following general formula (1): The non-aqueous electrolyte secondary battery, characterized in that contained in the battery cell. [Formula 1] (Wherein, X m + represents an organic cation, an alkali metal cation, or an alkaline earth metal cation having N + , P + , or S + , m is a valence of X, and n satisfies n = m. Is a natural number.) |
