摘要:
This invention uses as the anode active material (2) a zinc alloy containing Ni, at least one element selected from In, Pb, Ga and Cd and, optionally further, one element selected from Al, Mg, Ca, Ba and Sr for the anode of a conventional zinc-alkaline battery which employs zinc (2) as the anode active material, aqueous alkaline solution as the electrolyte, and manganese dioxide, silver oxide, oxygen and so forth as the cathode active material (5). The use of such zinc alloy permits the reduction of the amount of mercury to be used for amalgamation of the anode zinc surface which is made for the purpose of corrosion inhibition, thereby enabling the provision of a low-pollution zinc-alkaline battery.
摘要:
Active anode materials comprising amalgamated zinc powder for use in cells, in which the corrosion of zinc is effectively inhibited by a smallest possible amount of mercury, may be produced by a process comprising atomizing molten zinc added with mercury to obtain pre-amalgamated zinc powder and bringing the thus obtained powder, which is dispersed in a liquid, into contact with mercury or an amalgam to further amalgamate said pre-amalgamated zinc powder.
