PURPOSE:To obtain a cathode which has superior property, a long life and easy manufacturing by including a metal in a cell, which works as a cathode, together with a binding agent adhered by coating to a conductive porous material, if necessary, pressurized without sintering. CONSTITUTION:A layer made of a metal such as nickel and a binding agent is formed at least on one of the faces of a conductive porous material consisting of screen, expanding metal, panting metal or foaming metal etc. and is included in a cell without sintering process. If more strength is needed, it may well be pressurized after it is dried. Highpolymer materials, for example,car boxymethlcellulose, polyvinylalcohol, polyvinyl chloride and polyethlene etc. are used as binding agents. Thereby, it enables to get a enough strength as a pole and enables also to keep a good efficiency for a long time because it is not sintered at high temperature. |
