MoO3/PANI coaxial heterostructure nanobelts by in situ polymerization for high performance supercapacitors

Design and construction of three-dimensional CuO/polyaniline/rGO ternary hierarchical architectures for high performance supercapacitors

“…Enlarging the cell voltage and/or specific capacitance is thought to be an effective way to get high energy density for supercapacitors. In general, high surface area and excellent electrical conductivity are strongly beneficial for achieving high energy density for the hybrid pseudocapacitance electrodes with carbonaceous materials including activated carbon [5,6], carbon nanotubes or nanofibres [7e9], graphene [10e13], and conducting polymers [14,15]. The porous hybrid carbonaceous electrodes can not only enhance the specific capacitance and cycle ability, but also contribute large electrolyteeelectrode interface for charge smooth diffusion.…”

High Energy Density Ternary Composite Electrode Material Based on Polyaniline (PANI), Molybdenum trioxide (MoO3) and Graphene Nanoplatelets (GNP) Prepared by Sono-Chemical Method and Their Synergistic Contributions in Superior Supercapacitive Performance

“…Jiang et al [30] developed the MoO 3 /PANI coaxial heterostructure nanobelts which showed specific capacitances of 714 F/g at 1 mV/s scan rate and 632 F/g at 1A/g current density, far better in values than those for original α-MoO 3 nanobelts at the same conditions due to synergetic effect of both PANI and α-MoO 3 nanobelts. Chang et al [31] studied the specific capacitance of the asymmetric supercapacitor employing self-assembled reduced graphene oxide (RGO)/MnO 2 composite and RGO/MoO 3 composite as the positive and negative electrodes, respectively.…”

Self-templating Scheme for the Synthesis of Nanostructured Transition-Metal Chalcogenide Electrodes for Capacitive Energy Storage

“…1,[7][8][9] Previously developed pseudocapacitors have been based on transition metal oxides, hydroxides and conducting polymers which invariably suffer from either low conductivity or poor electrochemical stability, largely limiting their applications. [10][11][12][13][14] Therefore, it is imperative to create alternative pseudocapacitive materials with low cost, desirable electrical conductivity, highly porous structure, high specific surface area, desirable ionic permeability, large capacitance and good electrochemical stability. 15,16 Due to their unique structural features including well-defined interior voids, low density, low coefficients of thermal expansion, large surface area and surface permeability, hollow micro/nanostructured binary transition metal sulfides such as nickel sulfide and cobalt sulfide 3 have been widely investigated as a new class of pseudocapacitive electrode materials.…”
