纳米二氧化锰与超级电容器

Nano manganese dioxide and supercapacitor

锰基化合物贮量相对丰富,价格低廉,而且二氧化锰的基础研究较为透彻。因此,开发纳米二氧化锰超级电容器有着良好的基础和较大的实用意义。优质超级电容器的正极材料,其性能取决于纳米二氧化锰的形态(粒、棒、线、管)、宏观结构(晶体结构或无定形)、微观结构(孔径、孔隙率、比表面积);这些因素又互相关联,取决于制备方法与反应条件的选择。

Relatively speaking,manganese-based compounds are aboundent and cheap,and the properties of MnO2 are well known,so the development of nano-manganese dioxide supercapacitor has a good foundation and may result in potential applications.As a good anode material for nano-MnO2,it depends on the morphology of nano-MnO2（such as particle,rod,line,and tube）,macro-structure（crystal structure or amorphous）,micro-structure（pore diameter,porosity,special surface area et al）.All these factors are related to each other,and depend on manufacturing methods and reaction conditions.
