Activated Carbon Based Ruthenium Oxide Materials for Supercapacitor

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。

Abstract:

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.
