Electrochemical Pseudocapacitors Based on Ternary Nanocomposite of Conductive Polymer/Graphene/Metal Oxide: An Introduction and Review to it in Recent Studies

“…The specific power and energy output referring to typical contemporary supercapacitors and batteries, respectively, are depicted in Figure . As can be seen in the figure, supercapacitors generally provide not only more specific power but also appropriate specific energy in comparison with batteries ,,,…”

“…As can be seen in the figure, supercapacitors generally provide not only more specific power but also appropriate specific energy in comparison with batteries. [3,6,8,9] In general, according to the related charge storage mechanisms and the utilization of active electrode materials, the supercapacitor electrode materials can be categorized into three classes. [10,11] The first one contains an electrical double layer of active materials, called electrical double layer capacitors (EDLC), in which the charges are physically accumulated on the limited surface of the electrode materials through adsorbing-desorbing charged ions moving from an electrolyte onto high surface area electrodes constructing a double layer structure, usually composed of different carbonbased materials such as carbon nanofibers and nanotubes, activated carbon (AC) and graphene ( Figure 2).…”

Carbon nanotube/metal oxide dispersed poly(ortho‐aminophenol) as a ternary nanocomposite film: Facile electrosynthesis, surface characterization, and electrochemical pseudocapacitive performance

“…Diverse results with regard to the conductivity of the POAP film have been reported in the literature, demonstrating that the experimental procedure used for the production of the polymer film, as well as the purity of the starting monomer and dopant anions, is able to strongly influence the electrochemical response of POAP . Through the addition of nanoscale inorganic fillers, which possess interesting properties due to their nanosize and large surface area, the electrical and dielectric properties of conductive polymers can be modified . The capacitive performance of electrochemical capacitors is primarily dependent upon the physical and chemical properties of the electrode material.…”

“…[8] Through the addition of nanoscale inorganic fillers, which possess interesting properties due to their nanosize and large surface area, the electrical and dielectric properties of conductive polymers can be modified. [8][9][10] The capacitive performance of electrochemical capacitors is primarily dependent upon the physical and chemical properties of the electrode material. Innumerable compounds have been investigated as possible electrode materials by the evolution of nanotechnology, including ecofriendly transition-metal oxides (TMOs) such as ZnO, [11] Co 3 O 4 , [12] MnO 2 , [13] and NiO, [14] because they are naturally abundant and cost effective, and show fast and reversible redox reactions to store charges.…”

Electroactive Conjugated Polymer / Magnetic Functional Reduced Graphene Oxide for Highly Capacitive Pseudocapacitors: Electrosynthesis, Physioelectrochemical and DFT Investigation

“…Pyrrolidinium compared to imidazolium indicated larger electrochemical stability window (ESW) favorable for SCs operating at higher voltage or contributing mainly to the energy density. While Imidazolium actually provides higher ion conductivity with lower viscosity [30][31][32][33].…”
