“…Methods to create these heterodoped materials include chemical vapour deposition, pyrolysis with a hetero precursor and self-doping [ 2 ]. Pseudocapacitance can also be added through polymer functionalisation, with polyaniline (PANI) being one of the most commonly used polymers [ 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 ].…”

As worldwide energy consumption continues to increase, so too does the demand for improved energy storage technologies. Supercapacitors are energy storage devices that are receiving considerable interest due to their appealing features such as high power densities and much longer cycle lives than batteries. As such, supercapacitors fill the gaps between conventional capacitors and batteries, which are characterised by high power density and high energy density, respectively. Carbon nanomaterials, such as graphene nanoplatelets, are being widely explored as supercapacitor electrode materials due to their high surface area, low toxicity, and ability to tune properties for the desired application. In this review, we first briefly introduce the theoretical background and basic working principles of supercapacitors and then discuss the effects of electrode material selection and structure of carbon nanomaterials on the performances of supercapacitors. Finally, we highlight the recent advances of graphene nanoplatelets and how chemical functionalisation can affect and improve their supercapacitor performance.

“…These supercapacitors exhibit a higher specific power when compared to lithium-ion batteries. The electrodes of these supercapacitors are materials that are based on metal oxides but mainly on conductive polymers [87][88][89][90]. These conductive polymers have shown an excellent specific capacity and their low cyclic stability has been lately overstated by the investigation of nanocomposites which was based on conducting polymers [91][92][93].…”

With the development of wearable electronic devices, there has been extensive research interest in portable energy supply systems. In this study, traditional cotton fabrics are finished with a water repellent coating and a single-sided polyurethane (PU) coating to impart hydrophobicity. The hydrophobic lightweight cotton fabric can float on the surface of the pyrrole polymerization system solution. With increasing polymerization time, the pyrrole continues to polymerize and deposit on the side in contact with the fabric, resulting in a one-sided conductive fabric.The highest doping level was obtained for the polypyrrole (PPy) coating for polymerization time of 12 h. For PPy coating thickness of 18 μm, the square resistance was as low as 220 Ω/sq. The PPy-12 fabric electrode showed excellent electrochemical performance and cycling stability. An interdigitated pattern was etched on the surface of the one-sided conductive fabric (PPy-12) using a N, Ndimethylformamide solution. Fabric micro-supercapacitors were obtained by assembling with a H 2 SO 4 /PVA gel electrolyte. The fabric micro-supercapacitor exhibited good flexibility and electrochemical energy storage properties. For current density of 0.08 mA/cm 2 and power density of 19.1 μW/cm 2 , the energy density of the device was 0.09 μWh/cm 2 . After 3000 cycles, the micro-supercapacitor retained approximately 85% of the capacitance. Thus, fabric-based flexible microsupercapacitors have excellent application potential in the field of energy storage.
