PURPOSE:To obtain high capacity and long charge-discharge cycle without dissolution and decomposition by using an electrode obtained by accumulating carbon on a conductive substrate of high porosity metal by a vapor accumulation methode by low temperature heat decomposition. CONSTITUTION:A carbon accumulation is formed on a conductive substrate having high porous three dimensional structure by a vapor accumulation method, for example, low temperature heat decomposition at 1500 deg.C or less of hydrocarbon, and the carbon obtained is used as an electrode for charge carrier. As the conductive substrate, foamed metal having three dimensional structure, cotton-like metal, net-like metal, or a sintered metal plate having a porosity of 60% or more is used. The carbon in which the spacing of carbon layer is 0.337-0.355nm, and the intensity ratio of peak intensity of 1,580cm<-1> of Raman sectrum to that of 1,360cm<-1> is 0.4-1.0 is used. |
