Metal oxide materials are employed as electrodes for Faradaic capacitors, a typical representative of metal oxides is hydrated RuO2, which can yield a capacitance as high as 768 F·g-1 in H2SO4 electrolyte for a single electrode. However, it has a relatively high cost and this will prevent broader commercial applications; Besides, if RuO2 contacts with H2SO4 electrolyte for a long time, it may dissolve at a certain extent; at the same time, H2SO4 electrolyte can erode current collector, which cause entironment pollution.

赝电容器主要是以金属氧化物为电极材料，典型代表为RuO2，无定型RuO2在H2SO4溶液中单电极的比电容高768F·g-1 ；但由于Ru是贵金属、价格昂贵、难于实现商业化，并且RuO2长时间接触硫酸电解液，会出现一定程度的溶解，同时硫酸很容易腐蚀集流体，造成环境污染。
