In this study, Fe‐doped polyaniline/dye‐functional composite modified carbon felt electrode was synthesized using hydrothermal method and a supercapacitor exhibiting 1.5 V was obtained with 3.0 M KCl aqueous electrolyte. In order to improve supercapacitor performance easily and effectively, the effect of Lanaset Green B (LGB) acidic dye concentration on supercapacitor performance in polyaniline polymerization was investigated. Electrochemical, morphological and structural characterizations of the synthesized electrodes (CFt/Fe‐PANI/LGB) were carried out. The results showed that the capacitance increases due to the strong interaction of functional groups between PANI and dye molecules and improves the properties of pseudocapacitive supercapacitors by providing potential redox materials. The CFt/Fe‐PANI/LGB(3 mM) electrode displayed a high specific capacitance of 1543 F g−1 at a scan rate of 5 mV s−1 in half‐cell electrode system. In full‐cell, the assembled symmetric supercapacitor has a maximum energy density of 32.7 Wh kg−1 and power density of 1250 W kg−1. The supercapacitor electrode and symmetric supercapacitor display retention of capacitance performances 82.3 % and 78.8 % after 2400 and 5000 cycles in 3.0 KCl electrolyte, respectively. CFt/Fe‐PANI/LGB(3 mM), flexible, wearable carbon felt electrode material and improved redox behavior of the polymer material play an important role for textile electronics applications.

“…Recently, the template mediated facile strategical approach was developed and put forward to design hybrid nano‐manganese‐iron‐oxides with unique three‐dimensional porous structures utilized for supercapacitor applications 12 . Wang et al 13 developed parallel manganese oxide//hollow parallel Iron (III) oxide‐hydroxide and proposed its applications for asymmetric supercapacitors. Interestingly, diatomite skeleton was skillfully utilized to fabricate nano Iron (III) oxide‐hydroxide followed by the polymerization of pyrrole to create fine interaction for supercapacitors 14 .…”

Summary Nanocellulose materials are promising sustainable and environmentally friendly candidates for green and renewable energy storage applications. Herein, hierarchical Co3O4@CNC nanohybrid structure was fabricated in conjunction with cobalt acetate tetrahydrate and cellulose nanocrystals (CNC) as a bio‐carbon source using green ball‐milling pathway for the first time. For comparison, pristine Co3O4 nanostructure was prepared using a similar method without adding CNC. The structural and morphological characteristics of nanohybrid composites were investigated using X‐ray diffractometer (XRD), Raman, X‐ray photoelectron spectroscopy (XPS), Fourier‐transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Brunauer‐Emmett‐Teller (BET) techniques. Furthermore, the electrochemical properties of the nanohybrid composites evaluated using cyclic voltammetry (CV), Galvanostatic Charge‐Discharge (GCD), and electrochemical impedance spectroscopy (EIS) techniques. The hierarchical Co3O4@CNC nanohybrid electrode showed the highest specific capacitance of 396 F/g that of pristine Co3O4 nanostructure electrode (was 268 F/g) at a current density of 1.0 A/g for a three‐electrode assembly. The hierarchical Co3O4@CNC nanohybrid electrode showed appreciable capacitive behavior with 96% cyclic retention even after 5,000 cycles at 1.0 A/g with energy density of 12.5 Wh k−1 at a power density of 230.5 W k−1. Thus, it is suitable for improving and/or designing active electrocatalysts for enhanced supercapacitor applications.

“…The burning of fossil fuels has also caused a series of environmental crises such as global warming and air and water pollution. In order to solve the problems of climate change and energy shortage caused by the depletion of fossil fuels and related carbon emissions, developing novel energy storage devices such as solar cells [7], fuel cells [8], lithium-ion batteries [9,10], and supercapacitors [11,12] is undoubtedly one of the best strategies [13,14]. Among them, lithiumion batteries have received considerable attention due to its merits including high energy density, low self-discharge, lighter weight, no memory effect, and long life [15].…”

As a typical transition metal oxide anode material, ZnMoO 4 can deliver a higher theoretical capacity of 951.6 mAh g −1 due to its variable oxidation state and alloying reaction. However, lower conductivity and huge volumetric expansion restrict its further development. Herein, the modified sol-gel method is applied to synthesize a series of (1-x)ZnMoO 4 -xZnFe 2 O 4 (x = 0.1, 0.2, 0.3, 0.4, and 0.5) composites. The effects of compound proportion of ZnFe 2 O 4 on the crystal phase structure and morphology for ZnMoO 4 have been investigated in detail. All the composites have been conducted on electrochemical measurements, and the results illustrate that the composites display better electrochemical performance than that of ZnMoO 4 . Especially for 0.6ZnMoO 4 -0.4ZnFe 2 O 4 , it can deliver a capacity of 550.7 mAh g −1 after 500 cycles at a current density of 200 mA g −1 . Moreover, it also presents the higher capacity at higher current density. The improvement of electrochemical performance should be attributed to the synergistic effect of ZnFe 2 O 4 and ZnMoO 4 .
