摘　　要：超级电容器作为一种新型的储能装置,具有长寿命、高功率等特点,在诸多领域内有广泛的应用前景。在影响超级电容器性能的所有因素中,电极材料的性能起着决定性的作用。二氧化锰(MnO2)具有原料易得,价格低廉,来源广泛,环境友好等优点。综述了MnO2超级电容器电极材料的储能机理,纳米MnO2的微观结构与电化学特性之间的关系,并从纳米MnO2的制备及其综合改性角度,综述其合成、掺杂改性、复合方法在MnO2基电极材料的新进展,指出了MnO2基超级电容器电极材料的主要研究方向。As a novel energy storage system, supercapacitors with characteristics of long cycle-life and high rate charge discharge capability, can be applied in many fields. The performance of the electrode material is the most important factor affecting the nature of supercapacitor. MnO2 has advantages in price, environmental friendliness, and easy access. The energy storage mechanism of manganese dioxides electrode materials for supercapacitor was described, and the relationship between nano manganese dioxide microscopic structure and its electrochemical properties was analyzed. The recent developments of synthesis, doping modification, and compounding methods of manganese dioxide-based materials were reviewed from the angle of nanometer manganese dioxides preparation and its comprehensive modification. The main development directions of manganese dioxide-based electrodes for EC application were presented.
