MANUFACTURING METHOD OF POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a new power storage device which uses a lubricant to store an electrode assembly in a case.SOLUTION: When a secondary battery is manufactured, a case 10 where a lubricant is applied to an inner surface 10A is prepared in a case formation step and then an electrode assembly 20 is stored in the case 10 in an electrode assembly storage step. That is, the lubricant used in the case formation step is utilized in the electrode assembly storage step. The utilization of the lubricant is a new method that is not used in a conventional technique. The method eliminates the need of separately preparing the lubricants in the case formation step and in the electrode assembly storage step and thus reduces work hours and costs required for the preparation.
