METHOD OF MANUFACTURING POWER STORAGE DEVICE AND ELECTRODE ELEMENT MANUFACTURING APPARATUS FOR THE POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To facilitate manufacturing by reducing the alignment accuracy of members overlapped with each other.SOLUTION: A method of manufacturing a power storage device includes: a step of manufacturing an electrode element by overlapping positive electrodes and negative electrodes which are electrodes with each other so as to be alternately arranged through a separator; and a step of sealing the electrode element together with an electrolyte in an exterior body. A step of manufacturing the electrode element includes: a step of forming the electrode by processing an electrode preparation body into a predetermined shape using a processing tool for electrode; a step of holding the electrode using an electrode holding mechanism whose mutual physical relationship with the processing tool for electrode is fixed; a step of bonding the electrode held by the electrode holding mechanism to a separator preparation body; and a step of forming a separator by processing the separator preparation body into a predetermined shape using a processing tool for separator whose mutual physical relationship with the processing tool for electrode is fixed, while holding the electrode by the electrode holding mechanism after bonding the electrode to the separator preparation body.
