Recently, transition metal/metal oxides (TMMOs) decorated on porous carbons (PCs) have been intensively focused on designing rational electrode materials for the promising future specific category of electrochemical energy storage and conversion technologies. In particular, TMMO incorporation with PC structures has become very attractive in the area of supercapacitors (SCs) mainly caused by their large accessible surface areas (SSA), together with the suitable pore size distributions (PSD), high electrical conductivity, and rapid redox reactions reversibly on the surface. The transportation of ions, as well as electrons in the bulk of electrodes, is fast as a result of optimal contact between electrodes and electrolytes at the electrode–electrolyte interface, thereby generating high specific capacities (C sp) of these PCs with TMMOs. We report a survey regarding recent advances in the fabrication and synthesis of TMMOs decorated on PCs with some physical characteristics and their applications for electrochemical capacitors. Some future trends and prospects for further development of the subject nanocomposites in application to next-generation supercapacitors are discussed.

“…Flexible supercapacitors are representative promising electrochemical devices that offer a power supply for portable and wearable electronic devices 4 . In order to obtain flexible supercapacitors with enhanced electrochemical performance, many transition metal oxides, 5, 6 carbon nanomaterials 7, 8 and conducting polymers 9, 10 have been used for electrode materials for such supercapacitors. Among them, polypyrrole (PPy) as a practical conductive polymer has been one of the most used electrode materials for supercapacitors because of its low cost, easy preparation and environmental friendliness 11–14 …”

Treated carbon cloths combined with polypyrrole (PPy) nanowires (TCC@PPyW) were fabricated by template‐free electrochemical deposition of pyrrole in the presence of sodium citrate dihydrate and sodium perchlorate. The morphologies and electrochemical performances of the samples were studied using scanning electron microscopy, cyclic voltammetry, galvanostatic charge–discharge measurements and electrochemical impedance spectroscopy. The morphologies of PPy nanostructure were controlled by regulating interfacial pH, deposition time and concentration of sodium perchlorate. PPy nanorods were generated with the aid of water oxidation when the pH of pyrrole solution was 7.9, and PPy nanowires could be obtained by increasing the deposition time or the concentration of sodium perchlorate. The resulting PPy nanowires were about 100 nm in diameter and up to 600 nm in length. TCC@PPyW electrodes provided a large contact area for electrolyte, which facilitated the rapid delivery of electric charge. As a result, the TCC@PPyW electrodes exhibited a high areal specific capacitance of 841.2 mF cm−2 at 0.4 mA cm−2 and a high energy density of 420.6 μWh cm−2 at a power density of 0.2 mW cm−2. An all‐solid‐state flexible symmetric supercapacitor without any binder, incorporated with TCC@PPyW as electrodes and poly(vinyl alcohol)–LiCl gel as gel electrolyte, is also reported. The TCC@PPyW supercapacitor displayed excellent flexibility and rate capability. © 2021 Society of Chemical Industry
