Characteristics of conventional alloyed zinc powders for use in a cell can easily be improved into those of powders suitable for use in the cell which are low in hydrogen gas generation by mixing powders of a trivalent metal, for example, Bi or In, to the conventional alloyed zinc powders for use in the cell, preferably by in a range of 50 to 1000 ppm, under a dry condition.

The zinc or zinc alloy powder preferably has a particle size within the range of 10 &mgr;m to 1000 &mgr;m. The bismuth-coated zinc powder particles are obtained by immersing a mixture of a zinc powder and a metallic bismuth powder in an aqueous alkaline solution to deposit bismuth on surfaces of the zinc powder particles by displacement.

Abstract: A novel primary or secondary battery whose active material for the negative electrode is composed of metallic gallium, gallium alloys or gallium oxide has first come into the world.Gallium has an electrochemical equivalent of 23.24, which is smaller than those of zinc (32.70) and cadmium (56.21). This indicates that when used as an active material for the negative electrode in batteries, gallium has larger capacity per unit mass than zinc and cadmium by respective factors of ca. 1.4 and 2.4. The potential of the reaction; Ga+6OH.sup.- =GaO.sub.3.sup.3- +3H.sub.2 O+3e.sup.- is obviously less noble than the voltage of hydrogen evolution and this means that a high-potential battery can be made. Due to the high hydrogen overvoltage of gallium, gallium ions in the solution can be precipitated as metallic gallium by electrodeposition. As a further advantage, no dendrite formation occurs during the electrodeposition unlike in the case of zinc.
