PROBLEM TO BE SOLVED: To uniformly dope an electrode with ions.SOLUTION: A negative sheet 13 is provided on one outermost layer of an electrode sheet group 11, and a negative sheet 14 is provided on the other outermost layer. The negative sheet 13 includes a negative electrode collector 21, and one surface of the negative electrode collector 21 is coated with a negative plied timber layer 22 and the other surface thereof is provided with a metallic lithium foil 24 with a conductive layer 23 in between. In the same way, a negative sheet 14 includes a negative electrode collector 25, and one surface of the negative electrode collector 25 is coated with a negative plied timber layer 26 and the other surface thereof is provided with a metallic lithium foil 28 with a conductive layer 27 in between. Thus, the metallic lithium foils 24 and 28 can be arranged opposite to each other on the entire area of the negative electrode plied timber layer 22 and 26, and the negative electrode plied timber layers 22 and 26 can be uniformly predoped with lithium ions. |
