“…The maximum gravimetric capacitance of CC@PANI NTs-H is 438 F g −1 , which are larger than that of CC@PANI NTs-R (276 F g −1 ), respectively. The values are superior to most similar electrodes [18,[24][25][26][27][28], as shown in Table 1. The better electrochemical performances of the CC@PANI NTs-H electrode in comparison with CC@PANI NTs-R can be attributed to acid doping at high temperature, which promotes the ordered structure of PANI and provides more sufficient protons [29].…”

Carbon materials have been widely used in designing supercapacitors (SCs) but the capacitance is not ideal. Herein, we synthesize polyaniline (PANI) nanotubes on the basis of a carbon cloth (CC) through a one-step self-degradation template method, and fabricate a CC@PANI NTs-H (CC@PANI nanotubes doping at high temperature) composite electrode by thermal acid doping. The CC@PANI NTs-H electrode obviously exhibits better electrochemical performance with a gravimetric capacitance of 438 F g −1 and maintains 86.8% after 10,000 cycles than the CC@PANI NTs-R (CC@PANI nanotubes doping at room temperature) electrode. Furthermore, we assemble a flexible solid state supercapacitor (FSSC) device with the as-prepared CC@PANI NTs-H composite electrodes, showing good flexibility and outstanding electrochemical performances with a high gravimetric capacitance of 247 F g −1 , a large energy density of 21.9 Wh kg −1 , and a capacitance retention of 85.4% after 10,000 charge and discharge cycles. Our work proposes a novel and easy pathway to fabricate low-cost FSSCs for the development of energy storage devices.

“…The scan rate used for potentiodynamic deposition to prepare the individual electrode for supercapacitor fabrication is 2 mV/s, respectively. It is xed based on the experimentation as it is discussed in our previous paper [27]. For bamboo and broomstick-based composites, the electrolyte's (sulphuric acid) optimal concentration was 0.6 M and 1 M, respectively.…”

In the present study, energy harvesting is done from carbon fibers (CFs) synthesized using a naturally available broomstick and bamboo stick. The broom and bamboo sticks have been reprocessed in an alkaline solution using a controlled hydrothermal method. The carbonization of the cellulose fibers resulted in the production of CFs. The synthesized CFs have been used to prepare a ternary composite electrode with MnO2 and polyaniline (PA). Thus, prepared ternary composite electrodes were used for the supercapacitor application. The Supercapacitor with a maximum specific capacitance (SC) of 373 F/g (from Broomstick) and 132 F/g (from the bamboo stick) was fabricated, which showed good cycling stability. The structural properties of the electrode materials were confirmed using X-ray diffraction, scanning electron microscopy, EDAX, BET adsorption-desorption experiment, and Fourier transform infrared spectroscopy techniques. The fabricated symmetrical electrode's supercapacitor properties were analyzed using cyclic voltammetry (CV), electrochemical impedance, and galvanostatic charge-discharge (GCD) cycling technique.
