PROBLEM TO BE SOLVED: To provide a method for uniformly doping negative electrode with lithium ions at low cost.SOLUTION: A method for manufacturing a power storage device including a positive electrode including a nitroxyl compound taking a nitroxyl cation partial structure expressed by the formula (1) in the state of being oxidized, and taking a nitroxyl radical partial structure expressed by the formula (2) in the state of being reduced, a negative electrode including an active material capable of reversibly absorbing and desorbing lithium ions, and an electrolyte, and arranged to use, as an electrode reaction on the positive electrode, a reaction expressed by the reaction formula (A) in which electrons are exchanged between the state of being oxidized and the state of being reduced comprises the steps of: sticking metallic lithium to the negative electrode; assembling the power storage device with the negative electrode; charging the power storage device so that the voltage of the power storage device becomes 3.0-4.0 V; and uniformly pre-doping the negative electrode with lithium ions by leaving it for three or more days after the charging. |
