Abstract
A method of manufacturing a nonaqueous electrolyte secondary battery includes: manufacturing a positive electrode sheet by forming a positive electrode active material layer, which includes trilithium phosphate, on a positive electrode current collector foil; accommodating the positive electrode sheet, a negative electrode sheet, and an electrolytic solution in a battery case; and charging a battery after the accommodation. During the manufacturing of the positive electrode sheet, a positive electrode active material is a composite oxide including at least lithium and manganese. During the manufacturing of the positive electrode sheet, a conductive additive is obtained by attaching at least one of manganese or manganese oxide to a surface of a carbon material.
