ABSTRACT:
A hydrogen storage electrode for use as an anode of an alkaline battery and a process for producing such electrode are disclosed. According to the process, firstly particles of hydrogen storage alloy powder with maximum particle size of 50 .mu.m is prepared. The alloy powder particles are then made into microcapsules by electroless plating with copper amounting to 10%-20% by weight with respect to the sum of the alloy powder and the plating copper. With an electric current collector placed in contact with the copper-plated alloy powder set in a die cavity of a molding press, the molding dies are closed to press and the copper-plated powder and the current collector for bonding them together thereby to form the hydrogen storage electrode. Pressure exerted during the pressing is applied to such an extent that the porosity of the resulting compact of the pressed alloy powder falls in the range of 10% to 25%.
