Abstract: An object of the present invention is to provide a nonaqueous electrolyte secondary battery including a monofluorotoluene-containing nonaqueous electrolyte with an improved overcharge-preventing effect. In a monofluorotoluene-containing nonaqueous electrolyte, when a specific fluorophosphate compound is contained, the overcharge-preventing effect of the monofluorotoluene can be improved. As a result, in the overcharged state of a nonaqueous electrolyte secondary battery including the monofluorotoluene-containing nonaqueous electrolyte, an increase in the battery surface temperature can be suppressed.
