Hybrid functional carbon electrodes for supercapacitors

Self-standing hybrid electrodes have been fabricated through the systematic combination of low cost capacitive materials, such as activated carbon (AC), with carbon nanotubes (CNTs) which provide high electrical conductivity and a structural matrix in place of heavy metal collectors. The nanotube matrix proved effective to utilize cheap AC as a capacitive material and dispersion should be the key to improve the performance further. 1
