Abstract
A nonaqueous electrolyte secondary battery is provided with: a positive electrode; a negative electrode that contains lithium titanate; a separator that is interposed between the positive electrode and the negative electrode; and a nonaqueous electrolyte that contains an electrolyte salt and a nonaqueous solvent. The nonaqueous solvent contains propylene carbonate, a chain carbonate A represented by general formula ROCOOR(wherein each of Rand Rrepresents an alkyl group having 2 or more carbon atoms), and a chain carbonate B represented by general formula ROCOOR(wherein Rrepresents a methyl group and Rrepresents an alkyl group). The volume fraction of the propylene carbonate in the nonaqueous solvent is within the range of 25-33% by volume; the volume fraction of the chain carbonate A in the nonaqueous solvent is within the range of 65-74% by volume; and the volume fraction of the chain carbonate B in the nonaqueous solvent is within the range of 1-10% by volume.
