| 摘 要： | 超级电容器因其功率密度高、环保性能优异等特点引起人们的兴趣。二氧化锰具有天然含量丰富、绿色环保、高比容量和晶体结构多样性等优点,是一种优良的电极材料。但二氧化锰的导电性能差,工作过程中结构不稳定等缺点严重影响了其电化学性能。本文对本课题组和国内外学者多年来对MnO2应用金属掺杂、硫化物、碳材料、导电聚合物复合、微观结构改性构建核壳结构等研究成果进行总结概括,并展望今后的工作研究方向和重点。

| Abstract: | Supercapacitors have attracted people's interest because of their ultra-high power density and excellent environmental performance.The manganese dioxide is an excellent electrode material.Due to it has the advantages of rich natural content,environmental protection,high specific capacity and crystal structure diversity.However,the MnO2 has low conductivity and the structural instability during the working process seriously affects the electrochemical performance.This paper summarizes the research of the study group and scholars at home and abroad for metal doping,complex sulfide,carbon material and conductive polymer composite,microstructure modification and core-shell structure recent years,and looks forward to the future research work direction and focus. |
