Abstract
Provided is a method of manufacturing a nonaqueous electrolyte secondary battery, the method including: constructing a battery assembly by using a positive electrode containing N-methyl-2-pyrrolidone and a nonaqueous electrolytic solution containing an oxalato complex compound. In the method, the battery assembly is constructed such that a following expression of 0.000036≤B/A≤0.001048 is satisfied, where A(ppm) represents a content of N-methyl-2-pyrrolidone per unit mass of a positive electrode active material layer, and B(mol/kg) represents a content of the oxalato complex compound per unit mass of a negative electrode active material.
