摘要
与蓄电池相比,超级电容器具有较高的比功率;与传统电容器相比,超级电容器具有较大的容量和较高的能量,且工作温度范围宽、循环寿命长。金属氧化物超级电容器的储能以法拉第准电容为主,其电极材料分为三类:贵金属氧化物、贱金属氧化物和复合型金属氧化物。综述了金属氧化物超级电容器的储能机理、制备及最新研究进展;介绍了电容器中电解液、隔膜材料和集流体的相关性能。
Supercapaeitors had higher power density compared with rechargeable battery and larger capacity, higher energy, broad operating temperature range and long cycle llfe compared with conventional capacitors. The energy storage of supercapaeitors of mental oxide was based on quasi-capacitor, the electrode materials were classified into three sorts： precious mental oxides, base mental oxides and composition mental oxides. The energy storage mechanism, preparation and the recent research progress in metal oxides supercapacitors were summarized. Meanwhile, the performance of electrolyte, membrane materials and collector materials were introduced.
