Carbon fabrics are the new generation promising electrode materials for super capacitors owing to their high electrical conductivity, high chemical stability and low thermal expansion. In this work, 2D-MoS2 nanostructures have been successfully deposited over the commercially available carbon fabric by hydrothermal approach, using silicontungstic acid as an additive. MoS2 nanostructures – carbon fabric was broadly characterized using XRD, FESEM and Raman Spectroscopy. XRD patterns indicated that the fabricated MoS2 nanoparticles can be indexed to hexagonal (2H) and rhombohedral (3R) phases. FESEM images revealed the formation of hierarchical 2D MoS2 nanosheets arranged in a nanosphere like morphology over the carbon fabric. The electrochemical behavior of the MoS2 - carbon fabric and commercially available bare carbon fabric were studied using cyclic voltammetry analysis with different scan rates. The MoS2-carbon fabric exhibited an excellent electrochemical performance with a specific capacitance of 441 F/g at a scan rate of 10mV/s. The good cyclic behavior with symmetric charging/discharging curves, constant specific capacitance for longer scan rates, suggesting that the MoS2- carbon fabric electrode is a potential electrode material for high power applications.

Purpose The purpose of this paper is to prepare a new modified activated carbon fibers (ACFs) of high specific capacitance used for electrode material of supercapacitor. Design/methodology/approach In this study, the specific capacitance of ACF was significantly increased by using the phenolic resin microspheres and melamine as modifiers to prepare modified PAN-based activated carbon fibers (MACFs) via electrospinning, pre-oxidation and carbonization. The symmetrical supercapacitor (using MACF as electrode) and hybrid supercapacitor (using MACF and activated carbon as electrodes) were tested in term of electrochemical properties by cyclic voltammetry, AC impedance and cycle stability test. Findings It was found that the specific capacitance value of the modified fibers were increased to 167 Fg-1 by adding modifiers (i.e. 20 wt.% microspheres and 15 wt.% melamine) compared to that of unmodified fibers (86.17 Fg-1). Specific capacitance of modified electrode material had little degradation over 10,000 cycles. This result can be attributed to that the modifiers embedded into the fibers changed the original morphology and enhanced the specific surface area of the fibers. Originality/value The modified ACFs in our study had high specific surface area and significantly high specific capacitance, which can be applied as efficient and environmental absorbent, and advanced electrode material of supercapacitor.
