| 摘要 |
A nonaqueous secondary battery comprising a positive electrode sheet having a layer mainly comprising a lithium-containing metal oxide, a negative electrode sheet having a negative electrode material mixture layer mainly comprising a negative electrode material laminated with a metallic material mainly comprising lithium, a nonaqueous electrolytic solution containing a lithium salt, and a separator, wherein the nonaqueous secondary battery is prepared by a process which comprises winding the positive electrode sheet, negative electrode sheet and separator; inserting the elements thus wound into a battery can; injecting said electrolytic solution into the battery can, sealing the battery can, and then ageing the battery, whereby lithium is previously intercalated in the negative electrode sheet to provide a nonaqueous secondary battery having a high discharge capacity and good charge-discharge cycle characteristics. <IMAGE> |
