摘要

利用纳米晶水合RuO2制备了工作电压为1.6 V的对称RuO2/RuO2超级电容器。基于活性电极材料的总质量，对称超级电容器在功率密度为500 W kg - 1时，能量密度为18.77 Wh kg - 1，具有良好的循环稳定性和功率性能。这些结果证明了将RuO2用于对称超级电容器或将RuO2作为负极用于高能量密度的非对称超级电容器的潜力。

A Symmetric RuO2/RuO2 Supercapacitor Operating at 1.6 V by Using a Neutral Aqueous Electrolyte

A novel symmetric RuO2/RuO2 supercapacitor with a high operating voltage of 1.6 V is built using the nanocrystalline hydrous RuO2. The symmetric supercapacitor exhibits an energy density of 18.77 Wh kg −1 at a power density of 500 W kg −1 based on the total mass of active electrode material and excellent cycling stability and power capability. These results demonstrate the potentialities of using RuO2 for symmetric supercapacitor or using RuO2 as negative electrode for asymmetric supercapacitor with high energy density.
