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.

Abstract

The rechargeability and crystal structure changing of electrolytic manganese dioxide(EMD) in MgSO_(4) 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-MnO_(2) structure of EMD was changed,the production was reversible and could be recharged to γ-MnO_(2) structure again which ensured the rechargeability of EMD.
