<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a compound capacitor negative plate, wherein cracks on a carbon mixture coating layer acting as a capacitor layer coating a surface of an negative plate or coming-off from the negative plate is prevented, and charge and discharge cycle life is extended in case of use as an negative plate of a lead acid battery. <P>SOLUTION: A fixing agent layer is formed on a surface of the negative plate by fixing agent solution, next, a coating layer of a paste-like carbon mixture containing two carbon materials consisting of a first carbon material having conductivity and a second carbon material having a capacitor function and at least a binder is formed on a surface of the negative plate, at least on an upper surface of the fixing agent layer, and then, the fixing agent layer is solidified by drying, and the carbon mixture coating layer is formed into a porous carbon mixture coating layer. <P>COPYRIGHT: (C)2011,JPO&INPIT |
