PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing apparatus of a lithium ion secondary battery having stabilized charging characteristics and life characteristics.SOLUTION: A stable positive electrode can be obtained by performing electrochemical reaction of a positive electrode in a large amount of electrolyte solution, prior to final completion as a secondary battery, and when a secondary battery is completed by using that positive electrode, a highly reliable secondary battery can be manufactured. Furthermore, when a secondary battery is completed by also performing electrochemical reaction of a negative electrode previously in a large amount of electrolyte solution, a highly reliable secondary battery can be manufactured.SELECTED DRAWING: Figure 1 |
