Abstract

There is provided a method of manufacturing a non-aqueous electrolyte secondary battery equipped with a wound electrode body that is formed by laminating and winding a positive electrode, a negative electrode, and a separator. This method includes preparing the wound electrode body including an uncoated portion of positive electrode active material layers and an uncoated portion of negative electrode active material layers, and not forming the positive electrode active material layers on at least a surface of a positive electrode current collector on a winding outer peripheral side thereof in a region that includes at least an outermost periphery of the positive electrode; structuring the secondary battery by accommodating the wound electrode body in a battery case; and subjecting the secondary battery to an aging treatment in which the secondary battery is retained within a temperature range that is equal to or higher than 60° C.
