Abstract
(a) A power storage device is prepared. (b) An evaluation jig is prepared. The evaluation jig includes an insulating tubular member and a conductive needle-shaped member. (c) A charge level of the power storage device is adjusted. (d) A positive electrode or a negative electrode is selected as a reference electrode. (e) An operation to insert the evaluation jig into the power storage device is performed. (f) The insertion operation is controlled to stop the tubular member when a tip end of the needle-shaped member comes in contact with an electrode different from the reference electrode. (g) Short-circuiting through the needle-shaped member is caused. (h) The power storage device is evaluated based on a state of the short-circuiting power storage device.
