PROBLEM TO BE SOLVED: To achieve high energy density, and provide a negative electrode having high capacity and superior cycle characteristics by forming metal or alloy or carbon material capable of the storage or the discharge of lithium into layer-like on a collector. SOLUTION: A negative electrode 5 is formed by successively laminating an In-plated layer and a graphite layer 4 on the surface of a negative electrode collector 3. A positive electrode active material layer 7 composed of LiCoO2 , acetylene black, and fluororesin are formed on the surface of an aluminum foil-made positive electrode collector 6 so as to be a positive electrode. Either of a separator 8 and a gasket 9 is polypropylene resin-made. As electrolyte, nonaqueous electrolyte, which is prepared by dissolving a predetermined amount of LiPF6 in equi-volume mixing solution of ethylene carbonate and diethyl carbonate, is used. |
