PURPOSE:To prevent deposition of cadmium to the part to be used as the current collecting end when cadmium is electrochemically deposited in a porous body, by spreading synthetic resin in the part to be used as the current collecting end and drying it. CONSTITUTION:When cadmium is electrochemically deposited on the surface of a porous plate having conductivity, synthetic resin is spreaded and dried on the surface of a porous plate to form the current collecting end where cadmium is not deposited. For example, epoxy resin adhesive is spreaded on the part to be used as the current collecting end of nickel plate steel punched metal and dried. This plate is immersed in cadmium sulfate solution and is subjected to electrolysis. The electrode obtained is passed between a press roll, and cut in the center of the part where the synthetic resin adhesive is spreaded to obtain unit plate to be assembled to a battery. |
