Abstract

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.
