摘要
文描述了一种氧化钌/活性炭复合电极材料的制备方法,并对不同条件下制备的材料的循环伏安特性、交流阻抗特性进行了比较。使用该复合材料组装的模拟电化学超级电容器单电极比容量达到359F/g,远高于普通活性炭材料。与氧化钌电极材料相比,氧化钌/活性炭复合材料的高功率放电特性则有了明显的提高。
A ruthenium oxide coated activated carbon (RuO2/C) was synthesized as a new electrode material for aqueous-electrolyte super-capacitor. Some laboratory-scale prototype capacitors were fabricated with the RuO2/actived-carbon electrode material and tested in term of capacitance and high power discharge for their electrochemical performance. these composite super-capacitors exhibited a satisfactory performance, such as the rated capacitance higher than 350 F/g, compared with that of single electrode material only.
