Abstract : In this patent sintered zinc powder battery electrodes are prepared by (1) rinsing zinc powder with a solvent that dissolves zinc oxide at a faster rate than it dissolves zinc and which is saturated with a water soluble salt having a higher melting point than zinc; (2) pouring off the solvent; (3) mixing the zinc with the water soluble salt used in step (1); (4) packing the mixture around a metal screen that is made of a metal which is an electrical conductor having a higher melting point than zinc; (5) heating the packed article at a temperature above 419C but below the melting point of the water soluble salt and the metal screen; (6) cooling the article; and, (7) soaking the article in water to remove the water soluble salt.
