In order to study the fast and efficient method of preparing electrode material ZnMn2O4, in this paper, oxalic acid was selected as the precipitator, oxalic acid dihydrate (C2H2O4•2H2O) as the chemical precipitator, manganese sulfate monohydrate (MnSO4•H2O) as the manganese source and zinc acetate dihydrate (C4H6O4Zn•2H2O) as the zinc source. The precursor was prepared by co-precipitation method. Then, ZnMn2O4 powders with mesoporous structure were obtained at different calcination temperatures. The phase of ZnMn2O4 powders at different calcination temperatures was characterized by XRD analysis. After considering the crystallinity and high temperature agglomeration, samples calcinated at 600oC were selected as the cathode material of the battery, and were characterized by SEM and TEM. The experimental results show that the electrode material ZnMn2O4 prepared by this method has high crystallinity, high preparation efficiency, energy saving, environmental protection and good dispersion.
