(57) [Summary] (Modified) [Purpose] To provide a non-aqueous electrolyte secondary battery which is easy to manufacture and has no decrease in discharge capacity due to charge / discharge capacity difference of a negative electrode, and a method for manufacturing the same. [Structure] An electrode plate containing a positive electrode active material is prepared, and is immersed in a liquid containing a lithiating agent such as butyllithium, phenyllithium, naphthyllithium, or lithium iodide to form a battery using the positive electrode plate. To do. Further, the battery is constructed after immersing the electrode body in which the positive and negative two electrodes are opposed to each other with the separator interposed therebetween in the liquid containing the lithiating agent. A non-aqueous electrolytic secondary battery in which an electrode body is inserted into a battery case 9, a liquid containing a lithiating agent is injected into the battery case 9, an electrolytic solution is added, and the battery is sealed to form a battery, and the same Manufacturing method. |
