摘　　要：应用循环伏安法、恒流充放电、X射线衍射研究了电解二氧化锰在MgSO4溶液中的可充性和充放电过程晶体结构的变化.结果表明:电解二氧化锰具有一定的电化学循环性能;经过初始几次充放电循环后,达到稳定状态;充放电过程电解二氧化锰的γ-MnO2晶体结构可逆地发生变化,保证了电解二氧化锰的可充性.The rechargeability and crystal structure changing of electrolytic manganese dioxide （EMD） in MgSO4 electrolyte were investigated by cyclic voltammetry, galvanostatic charge/discharge and X-ray diffraction. The results have shown that the EMD has good rechargeability; after several initial cycles, the charge and discharge became stability; after discharge, the γ-MnO2 structure of EMD was changed, the production was reversible and could be recharged to γ-MnO2 structure again which ensured the rechargeability of EMD.
