PURPOSE:To increase performance and productivity of a paste type negative plate by impregnating cadmium material as active material in a sintered substrate using nickel fibers obtained by stick-slip vibration cutting. CONSTITUTION:4-50mu nickel fibers are produced by stick-slip vibration cutting. The nickel fibers are distributed in a desired form and sintered to make a porous sintered substrate. A mixture of CdO and metal Cd are impregnated in the sintered substrate, and dried, then the thickness of the impregnated substrate is adjusted to form a paste type positive plate for alkaline storage battery. Since this sintered negative plate does not use a core metal and has large pore size, electrolyte flow is good and deterioration of electrode is decreased. |
