| 英文摘要 | The electrochemical behaviors of ferrocene (fc)-containing ionic liquid [bmim]bf4 were investigated in a system, which used ferrocene-containing ionic liquid as electrolyte, porous carbon as electrode materials. the cyclic voltammetry and constant current charge-discharge results indicated that redox reaction of fc happened in the porous carbon, and which was a diffusion-controlled, highly reversible redox reaction. the average specific capacitance of 0.01 mol.l-1 [bmim]bf4/fc at a current density of 1 ma-cm(-2) was 163 f.g(-1), 63% higher than that of pure [bmim]bf4. the increase of average specific capacitance indicates that the faradic pseudocapacitance associated with fc species in the redox reactions has a considerable contribution to the total capacitance of ecs (electrochemical capacitors). at the same time, it shows a power density of 400 w.kg(-1) as well as energy density of 3 7.5 wh.kg(-1) approaching the level of a practical battery. |
