A 10 years-developmental study on conducting polymers composites for supercapacitors electrodes: A review for extensive data interpretation

Surfactant-assisted morphology modification of nanostructured MnMoO4 for high-performance asymmetric supercapacitors

“…However, when p = 0.5, the charge storage is governed by the semi-infinite diffusion process. 53,54 The p -values of MMO samples are 0.74, 0.66 and 0.56 for MMO, MMO-P and MMO-C samples, respectively (Fig. S4, ESI†).…”

Recent Trends in Supercapacitor Research: Sustainability in Energy and Materials

“…[5,7,75,76] Typically, in a hybrid electrode, the carbon material improves the conductivity and surface microarchitecture, while the pseudocapacitance is due to oxides/hydroxides, sulfides and other metal compounds, and conductive polymers. [16,77,78] A range of carbon materials are considered substrates in such composites, including activated carbon cloth to create flexible electrodes (Mn(OH) 2 @AC and Fe 2 O 3 @AC, [79] CoNi-DHÀ S@CC, [80] c) CV curves in different potential windows at a scan rate of 100 mV s À 1 ; d) charge-discharge curves at various current densities; e) specific capacitances at different current densities.

“…Conductive polymers composed of conjugated structures, such as polyaniline (PANI), polypyrrole (PPy), polythiophene (PT) and its derivatives, have attracted the attention of researchers due to their high conductivity and low cost; however, due to a number of limitations, including low mechanical stability (swelling and compression) during the charge/discharge process, they have recently been used mainly to create hybrid composites with various materials, such as graphene, [51,58] transition metal oxides [103,148] and sulfides, [111] MXene, [149,134] and MOF, [143] to improve the functionality of both components of the resulting hybrid materials [10,75,78] (Table 6). Among conducting polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) is often used as a component of hybrid materials due to its high conductivity in the p-doped state (300 to 500 S cm À 1 ) and wide potential window of electrochemical stability (1.2-1.5 V) and higher chemical and thermal stability compared to other conducting polymers.…”

Graphene-Induced Enhanced Supercapacitor Properties of V2O5-GNPs Nanocomposites for Energy Storage Devices

“…The cyclic voltammetry investigations further revealed that the redox reaction is a diffusion-controlled process suggesting that this is likely the primary reason for the pseudocapacitive behavior observed with higher scan rates. The diffusion-controlled faradaic and non-diffusion-controlled battery-type processes of the synthesized electrodes were then examined using the two differentiation approaches, namely the Trasatti method [42] and the Dunn method [43]. The power law 𝐼 𝑃 = 𝑎𝑣 𝑏 in the Dunn technique is given by the peak current (𝐼 𝑃 ) vs scan rate (C).…”
