Study On Preparation Of Hg-free Zinc Powder For Alkali Manganese Battery

Our country is the biggest country which zinc manganese battery production is 200 hundreds million, and zinc for battery occupies 25% of total. Hg-free zinc powder is the key material to produce Hg-free alkali manganese battery, and it's hard task to develop alkali manganese Hg-free zinc powder to substitute the high-priced importing zinc powder, meet the demand of producing the Hg-free battery and reduce the producing cost.The research finds out the alloy across analyzing amalgamation, and deeply analyzes the influence of In, Bi, Pb, Ca, and Al on the zinc powder capability. Then, we find out the best directions for producing zinc powder. By the way, we do much work over the influence of the powder shape and granularity on the zinc powder capability.The atornization for producing zinc powder is designed on the basis of many literature and deep experiments. Moreover, the author optimizes the technique meters to solve how to control the shape and granularity and produce zinc powder which shape and granularity can meet the needs for producing battery.
