Discharge performance of free-mercury zinc alloy powders as anode materials for alkaline zinc manganese batteries

The AA-type alkaline zinc manganese batteries were assembled by using the different free-mercury zinc alloy powders manufactured by spraying technique as anode with better corrosion resistance, then discharged continuously at constant current. According to their discharge curves and discharge capacity, it shows that the Zn-1.0%In?Zn-0.20%Pb?Zn-0.1%In-0.1%Pb?Zn-0.1%In-0.2%Pb?Zn-0.10%In-0.05%Bi-0.005%Al(all percentages in formula are mole percentages) free-mercury zinc alloy powders have excellent discharging performance, the capacity is close to or higher than that of zinc powders made in Belgium.
