Zusammenfassung:	PROBLEM TO BE SOLVED: To solve such problems as much time to be required, thickness accuracy of an ultra-thin lithium metal foil with a thickness of 30 μm or less, handling or the like in a predoping technique that is believed to be highly practical and is an electrochemical method in which a battery is assembled while an active material (electrode) is brought into contact with lithium directly or the active material is short-circuited to the lithium via an electrical circuit, and then an electrolyte is injected to perform predoping.SOLUTION: A method for predoping lithium includes mixing a material capable of doping lithium with lithium metal in the presence of an solvent.
