摘要：

Fine zinc powder with dendritic microstructure is applied in preparation of cathode of zinc-air battery. Based on a series of experiments, the electrodeposition was determined for the preparation of zinc powder with dendritic microstructure in the solution system of Zn2+-NH4+-SO42--H2O. The main factors affecting the process such as current density, temperature, concentration of reactants and schedule of brushing powder were investigated comprehensively. The optimal process conditions are 15g/L Zn2+, 30 similar to 40g/L(NH4)(2)SO4, 800 Am-2 current density at 30 degrees C, with the schedule of brushing powder is 2 minutes. Based on the test results the optimal conditions, fine zinc powder with dendritic microstructure can be fabricated by electrodeposition.
