Further, improved charge storage/delivery properties can be provided by the aligned structured electrodes for effective participation in the charging/discharging process, as each of the constituent aligned tubes can be connected directly onto a common electrode. Another advantage of vertically-aligned CNTs is that, electrolyte access to the otherwise inaccessible inner cavity of the CNTs for charge storage can be accomplished by opening the top end-caps of the CNTs viz., plasma etching . Recent studies have reported the improved rate capability with enhanced energy density (148 Wh Kg -1 ) and power density (315 KW Kg -1 ) over randomly entangled CNTs. Specifically, vertically aligned CNT array electrode prepared by template-assisted CVD method in the presence of 1M H2SO4 exhibited a specific capacitance value of 365 F g -1 and the vertically-aligned CNTs electrode prepared by a template-free CVD approach showed a specific capacitance value of 440 F g -1 . CNTs (both randomly entangled CNTs and vertically-aligned CNTs) based supercapacitor electrodes exhibit low specific capacitance value (below 500 F g -1 ), due to the high contact resistance between electrode and current collector, and also due to its ineffective interaction with the electrolyte . Moreover, it is difficult, if the scale-up production of vertically aligned CNTs is not impossible to meet the demands of commercialization of supercapacitors. 1D Carbon nanofibers (CNFs) is another important carbonaceous material with size less than 1 mm, and has structure and properties similar to CNTs, whereas it has easier production, economic, and better functions .
