Polyethylenedioxythiophene and molybdenum disulfide nanocomposite electrodes for supercapacitor applications

High‐performance symmetric supercapacitor based on molybdenum disulfide/poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) composite electrodes deposited by spray‐coating

“…This capacitance is higher (73 F g −1 ) than for a published work citing supercapacitors with spraydeposited electrodes based on PEDOT:PSS/carbon cloth (CC) composites 37. Also, the specific capacitance is comparable (130-360 F g −1 ) to a work found in the literature for electrodes based on nanocomposites of MoS 2 /PEDOT prepared by the polymerization of EDOT in the presence of a MoS 2 dispersion, when measured in a two-electrode configuration using aqueous electrolyte 34. Moreover, the 3:1 supercapacitor displayed a specific capacitance just slightly lower (142.3 F g −1 ) than for a ternary nanocomposite electrode based on polyaniline/graphene/ MoS 2 cited in the literature, produced by much more complex and refined techniques than those used here 58.…”

“…Ge et al 33 reported a supercapacitor electrode based on MoS 2 /PEDOT:PSS composite films produced by filtration with a great volumetric capacitance of 141.4 F cm −3 and remarkably long‐term cyclability (98.6%). Nonetheless, Alamro et al 34 reported supercapacitor electrodes based on a chemically synthesized MoS 2 /PEDOT:PSS, reaching high specific capacitances ranging from 122 to 452 F g −1 . Despite the promising results, supercapacitors based on MoS 2 /PEDOT:PSS electrodes are fabricated using traditional techniques, which limits the scale production of the device.…”

Recent Advances in 2D-MoS2 and its Composite Nanostructures for Supercapacitor Electrode Application

“…The MoS 2 −PEDOT composite was obtained by a chemical oxidative polymerization technique using the monomer EDOT dissolved in a solution of 1 M HCl containing 2 mg mL −1 PSS. 256 This MoS 2 −PEDOT supercapacitor exhibited a high specific capacitance of 360 F g −1 in 2 M HCl acidic electrolyte solution with 52 Wh kg −1 and 4.8 kW kg −1 energy and power densities at a current density of 10 mA g −1, respectively. Wang et al fabricated a pizzalike MoS 2 /PPy/PANI hybrid electrode, where the synergistic effect between them gave excellent electrochemical performance compared to its individual electrodes.…”

Investigations on performance of PEDOT:PSS/V2O5 hybrid symmetric supercapacitor with redox electrolyte

“…where k is a constant with value 0.94 (assuming the nanoparticles to be spherical), λ is the wavelength of X ray source-Cu K plane bending, in plane symmetric stretching, stretching deformation vibrations, C=C symmetric and asymmetric vibrations, and so forth. 43,44 The Raman spectra of V 2 O 5 exhibits peaks at 103, 145, 197, 284, 405, 481, 528, 701, and 994 cm −1 which are characteristic peaks of α-V 2 O 5 . As mentioned before, V 2 O 5 exists as a layered structure with the packing of corner and edge-shared VO 5 polyhedralayers along the c-axis linked together by weak vanadium-oxygen interactions.…”
