PROBLEM TO BE SOLVED: To provide a manufacturing method of of a secondary lithium ion battery. SOLUTION: Carbon is turned into a cathode in a nonaqueous lithium ion conductive solution, and the carbon is wetted by the solution, and lithium sufficient to make inactivate even either active part in the carbon is electrochemically stuck to the carbon from the solution, and capacity of residual lithium sufficient to reversibly intercalate the quantity of a kind of reversible lithium is left in the carbon. In an electrolytic bath, a strip 6 is rolled out of a reel 10, and passes through under rollers 12 and 14, and is wound round a reel 16 after the transformation into lithium is caused in a tank 2. A counter electrode 8 contains the lithium, and supplies the lithium to electrolyte during transformation into lithium, and electrolytic dissociation of electrolyte 4 in the counter electrode 8 can be avoided thereby. |
