摘要

1.Introduction Various carbonaceous materials, including activated carbon[1] carbon aerogels[2], carbon nanotubest[3], microporons skeleton carbon[4] and mesoporous carbon (hard-templated)[5], have been investigated as electrode materials of supercapacitor. Among those carbons, common active carbon possesses limited surface area and mainly mieropores, which lead to low energy density and power output; carbon aerogel and carbon nanotubes has provided a good model system with large mesopores and high conductivity, leading to impressive power densities but low energy density due to their low surface area; Mieroporons skeleton carbon is prepared by chlorinating carbides using chlorine gas at high temperatures, whose preparation process is quite hazardous. Hard-templated mesoporous carbons provide reasonably good combination of energy density and power density due to their large surface area and relatively large pore size. However, the insufficient and unadjustable mieropores and long pathway of ionic diffusion in small mesopore channel (2-4 nm) hinders the further improvement of energy density and power density of these materials. Therefore, a carbon with more and tunable micropores, larger mesopores and appropriate micropore-mesopore architecture is expected to be a superior electrode material to hard-templated mesoporons carbon for EDLC applications.
