Abstract
Anode active materials comprising amalgamated zinc powder for use in cells, which may well achieve inhibition of corrosion of zinc with a smallest possible amount of mercury, may be produced by a process comprising atomizing a molten zinc added with mercury to obtain pre-amalgamated zinc powder and bringing thus obtained powder, which is dispersed in a liquid, into contact with mercury or an amalgam to further amalgamate said pre-amalgamated zinc powder.
