Influences of Different Methods of Electrode Fabrication On the Cyclic Voltammetric Behavior of Electrolytic Manganese Dioxide
摘 要
采用压制泡沫镍、石墨棒模具、粉末微电极三种电极制作方法研究电解二氧化锰在硫酸镁溶液中的循环伏安行为,并用X射线衍射法分析电解二氧化锰放电/充电后结构形态的变化.结果表明:用粉末微电极制作的研究电极在循环伏安扫描过程中反应灵敏、解析度好,所得循环伏安谱图中还原、氧化峰的变化与X射线衍射谱图中衍射峰的变化具有较好的对应关系,能更真实地反映电解二氧化锰的电化学性质.

Abstract
Effects of different methods of electrode fabrication,i.e.① method of porous nickel electrode pressed with thin pieces of electrode material;② graphite rod mould electrode;and ③ powder microelectrode,on the cyclic behavior of electrolytic manganese dioxide in solution of magnesium sulfate were studied.Changes of structural speciation of electrolytic manganese dioxide after discharge and charge were also studied by the X-ray diffraction method.It was found that high sensitive reactivity and good resolution were obtained in the cyclic voltammetric scanning by using the powder microelectrode;and that redox peaks in the cyclic voltammogram were in good consistency with the diffraction peaks in XRD patterns.Hence,the electrochemical property of electrolytic manganese dioxide was more accurately and truely revealed at the powder microelectrode.
