Characterization of alkaline manganese dioxide products containing no lead added zinc alloys
- Rayovac Corp., Madison, WI (United States)
Environmental pressures have resulted in major efforts by consumer battery manufacturers to significantly reduce the toxic heavy-metal content of alkaline manganese dioxide cells. The performance characteristics of mercury- and cadmium-free products containing no lead-added zinc alloys have been evaluated and compared to mercury and cadmium-free products containing lead-bearing alloys. The effects of the absence of mercury, cadmium and lead are reported. The efforts of the battery industry to deal with the observed problems is reflected in awarded patents and an abundance of patent applications involving the group of metals: bismuth, indium, gallium, thallium, calcium, aluminum, and strontium.
