PURPOSE:To improve an initial capacity and a cycle service life by transforming a carbonic material having a (n) type dope ability being used as a negative electrode into a material having a crystal structure in which carbon atom bonded polyhedral spherical molecules are arrayed. CONSTITUTION:A negative electrode 2 is composed of a rubber type crystallizing agent and carbon powder having a crystal structure in which polyhedral spherical molecules C60 are arrayed, and is brought into a pressure contact with a negative electrode current collecting body 6 of nickel net. A positive electrode 1 is composed of a positive electrode active material LiCoO2, carbon black and a a binding agent of fluorocarbon type resin, and is press-fitted to a positive electrode current collecting body 5 of aluminium net, and is arranged opposite to the negative electrode 2 through a separator 3. Thereby, a battery, whose self discharge quantity is small and which has a high capacity and has an excellent cycle performance, can be provided. |
