Anode and a secondary battery using the secondary battery

PROBLEM TO BE SOLVED: To increase the battery capacity in substance in the region of actual use of the battery, while maintaining a high charge and discharge efficiency and a good cycle characteristic. SOLUTION: In the negative electrode for secondary battery that can store and release lithium ion, a multi-layer structure including a first layer 2a made of mainly carbon and a second layer 3a made of mainly a membrane-shaped lithium storage material that can store lithium more than the theoretical capacity of lithium storage of carbon, is provided. And the membrane-shaped lithium storage material is selected from a group of Si, Ge, Sn, Pb, and an oxide of these.
