Abstract
Gassing is significantly reduced in electrochemical cells having anodes of metals, such as zinc, by reducing the number of grains in the particles of the polycrystalline metal to at least a third of the original number of grains and thereafter using the metal in the formation of the cell anode. Such grain number reduction is effected by heat treatment of the anode metal at a temperature below that of the melting point of the metal. Corrosion is further reduced with such reduced grain number particles and particularly with single crystal particles by the addition of small amounts of a gas inhibiting surfactant, for example, an organic phosphate inhibitor such as RA600 from GAF Corp. to the cell. Alternatively, or in addition, corrosion is reduced by prealloying the metal particles with small amounts of one or more of indium, thallium, gallium, bismuth, cadmium, tin and lead prior to reduction of the number of grains or the formation of the single crystal particles. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.
