摘要 金属氧化物电极兼有双电层电容和10~100倍双电层电容的准电容,其比容量远远大于活性炭材料表面的双电层电容,而且使用寿命长(循环次数10^5-10^6),维护简单,是一种新型、高效、实用的能量存储装置,引起研究者的广泛兴趣。综述了超级电容器用金属氧化物电极材料(RuO2、MnO2、Co3O4和NiO)及复合型氧化物电极材料的储能原理、制备和性能的研究现状,并且展望了超级电容器金属氧化物电极材料当前热点研究领域和发展前景。 Mental-oxide electrodes not only have double layer capacitance but also possess pseudocapacitance, hence, the specific capacitance is much larger than that of active carbon electrode, attracting extensive attention of researchers. Mental-oxide electrodes have long service life ( cycles : 10^5 - 10^6 ) and the maintenance is simple, so they are novel, efficient and practical energy storage devices. The energy storage mechanism, preparation, current performance research and development perspective of mental-oxide electrode materials( RuO2, MnO2, Co3O4and NiO) for supercapacitors as well as its compound were expounded.
