摘要
超级电容器作为储能元件 ,具有重要的战略意义 ,与常规的电解电容器相比 ,明显地提高了比容量、比能量 ;而与电池相比 ,虽然比能量较低 ,但其比功率却是电池的数量级倍数。目前用于制备超级电容器的极化电极材料主要分为碳素材料、金属氧化物材料和导电聚合物材料。简要地介绍了这三类材料的制备、结构、改性、工作原理以及电化学特性 ,评述了这三类材料的研究进展。这三类材料制作的电容器具有超大功率 ,长循环寿命等特点 ,为电动车 (EV)
s:Compared with conventional electrolytic, supercapacitor(electrochemical capacitor)improves the specific capacitance, the specific energy density dramatically. While compared with battery, the Supercapacitor has less specific energy density. There are three types of materials that can be used for manufacturing supercapacitors. They are carbon-based materials, metal oxide materials and conductive polymer materials. A brief description of the development of three types of materials is given, including preparation, structure, modification, working mechanism and electrochemical property of these materials. The recent development of these materials used for supercapacitors was reviewed.The capacitor made up with these three types of materials has characteristics of superhigh power and long circulation life.The electrode materials for supercapacitor make prepares for the need of the rising electric vehicles and other systems of energy management.
