“…As the current density continues to increase to 15 mA/cm 2 , the areal capacitance drops very little and finally keeps stable (∼149 F/g). It is noteworthy that the electrode maintained 77.2% retention of its initial specific capacitance measured at a high rate of 15 mA/cm 2 (23.3 A/g), which is superior to the previously reported values of other MnO 2 /carbon-based electrodes including MnO 2 /CNT@carbon microelectrode (gravimetric capacitance remains less than 50% with the increase of current density from 0.5 mA/cm 2 to 3 mA/cm 2 [21]), MnO 2 /CFP (75% retention from 1 A/g to 10 A/g [23]), and PPy/MnO 2 @carbon cloth (capacitance retention of 70% from 0.2 A/g to 5 A/g [24]). Moreover, the specific capacitance of MnO 2 /CC-40 min electrode is substantially higher than the value reported for MnO 2 nanosheets/carbon nanofibers (151.1 F/g at the current density of 1 A/g [15]).…”

MnO2 nanorod/carbon cloth (MnO2/CC) composites were prepared through in situ redox deposition as freestanding electrodes for flexible supercapacitors. The CC substrates possessing porous and interconnecting structures enable the uniform decoration of MnO2 nanorods on each fiber, thus forming conformal coaxial micro/nanocomposites. Three-dimensional CC can provide considerable specific surface area for high mass loading of MnO2, and the direct deposition process without using polymeric binders enables reliable electrical connection of MnO2 with CC. The effect of MnO2 decoration on the electrochemical performances was further investigated, indicating that the electrode prepared with 40 min deposition time shows high specific capacitance (220 F/g at a scan rate of 5 mV/s) and good cycling property (90% of the initial specific capacitance was maintained after 2500 cycles) in 1 M Na2SO4 aqueous solution. This enhanced electrochemical performance is ascribed to the synergistic effect of good conductivity of carbon substrates as well as outstanding pseudocapacitance of MnO2 nanorods. The obtained MnO2/CC compositing electrode with the advantages of low cost and easy fabrication is promising in applications of flexible supercapacitors.

Carbon Cloth‐based Hybrid Materials as Flexible Electrochemical Supercapacitors

Carbon cloths are the important materials composed of woven carbon fibres having the diameters in the range of 5–10 μm. These materials have been investigated for innumerable applications such as supercapacitors (symmetric and asymmetric), batteries, solar cells, and catalysis. They are found to be the best supports as supercapacitive materials by providing high surface area, conductivity and flexibility compared to much widely used substrate materials such as Ni foam and 1D Fe nanowires. High conductivity and surface area of carbon cloths enable ion diffusion and cause decrease in charge transfer resistance, resulting in an increase of specific capacitance of specific electrodes. Several supercapacitive metal oxides, chalcogenides, phosphides, MXenes, carbon nanotubes, graphene, and conductive polymers have been incorporated into carbon cloths to improve their energy storage activity. Further modification of carbon cloth surface via oxidation, doping and by the growth of different nanostructures is also helpful as it increases the electroactive surface area necessary for electrochemical interaction. The present review mainly focuses on the development of flexible supercapacitors using carbon cloth‐based substrate materials. Such flexible supercapacitors can be further utilized for an uninterrupted and steady power supply to wearable and portable electronic devices.

Nano-Mg(OH)2 is attracting great attention as adsorbent for pre-concentration and recovery of rare earth elements (REEs) from low-concentration solution, due to its superior removal efficiency for REEs and environmental friendliness. However, the nanoparticles also cause some severe problems during application, including aggregation, blockage in fixed-bed column, as well as the difficulties in separation and reuse. Herein, in order to avoid the mentioned problems, a carbon cloth (CC) supported nano-Mg(OH)2 (nano-Mg(OH)2@CC) was synthesized by electrodeposition. The X-ray diffraction and scanning electron microscopy analysis demonstrated that the interlaced nano-sheet of Mg(OH)2 grew firmly and uniformly on the surface of carbon cloth fibers. Batch adsorption experiments of Eu(III) indicated that the nano-Mg(OH)2@CC composite maintained the excellent adsorption performance of nano-Mg(OH)2 toward Eu(III). After adsorption, the Eu containing composite was calcined under nitrogen atmosphere. The content of Eu2O3 in the calcined material was as high as 99.66%. Fixed-bed column experiments indicated that no blockage for Mg(OH)2@CC composite was observed during the treatment, while the complete blockage of occurred to nano-Mg(OH)2 at an effluent volume of 240 mL. Moreover, the removal efficiency of Mg(OH)2@CC was still higher than 90% until 4,200 mL of effluent volume. This work provides a promising method for feasible application of nanoadsorbents in fixed-bed process to recycle low-concentration REEs from wastewater.
