  "textContent": "The present invention provides a nonaqueous electrolyte secondary battery that includes inside a battery cell: a positive electrode; a negative electrode prepared by using a negative electrode paste containing a silicon-based negative electrode active material; and a nonaqueous electrolyte solution, wherein an ionic compound represented by the following general formula (1) is contained inside the battery cell, wherein X represents an organic cation having N, P or S, an alkali metal cation, or an alkaline earth metal cation, m represents a valence of the X, and n represents a natural number satisfying n = m. As a result, there is provided a nonaqueous electrolyte secondary battery of which recovery characteristic between before and after high temperature standing is improved.",
