Abstract
A manufacturing method of a secondary battery, including: a preliminary charging of preliminarily charging at least one electrode body including a positive electrode material, a negative electrode material, and an electrolyte; one or more times of pressurizing of bringing the electrode body into a pressurized state by a mechanical pressure during a period of the preliminary charging and a period after the preliminary charging; and one or more times of pressure reducing of reducing a pressure in an atmosphere of the electrode body during a period of the preliminary charging and a period after the preliminary charging.
