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.

“…Recently, the introduction of heteroatoms (O/N/S) in carbon skeleton has effectively increased the specic capacitance of carbon electrode materials in water electrolyte. [14][15][16][17] The mechanism of capacitance increase may be the Faraday reaction with heteroatom functional groups and the increase of wettability of channels. 17 Considering the above factors, if a material has both homogeneous ultrapore and heteroatom, it should have good capacitance performance.…”

The ever‐increasing market for portable and wearable electronic devices creates a demand for high‐efficiency electrochemical energy storage devices with excellent flexibility. Herein, MOF‐derived porous Co3O4 scaffolds as the core, ultrathin NiO nanosheet‐arrays as the shell, well‐aligned core‐shell structured Co3O4@NiO were constructed on carbon cloth (CC/Co3O4@NiO) via facile chemical bath methods. Composition, morphological structure, and electrochemical performance of the hybrid nanomaterials were analyzed in detail. Benefiting from the MOF‐derived porous Co3O4 core, the NiO shell with large specific surface area, and close conductive linkages between the core and shell, CC/Co3O4@NiO presents an outstanding areal capacitance of 3015.1 mF cm−2 (1206 F g−1) at 5 mA cm−2 and an exceptional rate performance. Additionally, the flexible SASC device assembled with the CC/Co3O4@NiO cathode possesses an ultra‐high volumetric energy density of 3.11 mWh cm−3 at a volumetric power density of 116 mW cm−3 with a satisfactory cycling stability (90.1 % of after 10000 cycles). These values are superior to the great majority of the state‐of‐the‐art flexible electrochemical capacitors. Thereby, the core‐shell structured CC/Co3O4@NiO is a promising candidate material for energy storage devices, and this work can provide a reference for the structural design and constructing of electrode materials.
