Copper-based compounds have attracted increasing attention as electrode materials for rechargeable devices, but their poor conductivity and insufficient stability inhibit their further development. Herein, an effective method has been proposed to improve the electrochemical properties of the copper-based electrodes by coating carbon materials and generating unique micro/nanostructures. The prepared Cu2S/Cu7S4/NC with hierarchical hollow structure possesses excellent electrochemical performance, attributing to the composition and structure optimization. The superior charge storage performance has been assessed by theoretical and experimental research. Specifically, the Cu2S/Cu7S4/NC exhibits remarkably higher electrical conductivity and lower adsorption-free energy for O* and OH* than those of Cu2O. Moreover, the Cu2S/Cu7S4/NC delivers a high specific capacitance of 1261.3 F·g–1 at the current density of 1 A·g–1 and also has great rate performance at higher current densities, which are much better than those of the Cu2O nanocubes. In addition, the assembled hybrid supercapacitor using Cu2S/Cu7S4/NC as the anode exhibits great energy density, power density, and cycling stability. This study has proposed a novel and feasible method for the synthesis of high-performance copper-based electrodes and their electrochemical performance regulation, which is of great significance for the advancement of high-quality electrode materials and rechargeable devices.

“…When zinc chloride is washed with acid and water, the carbon becomes a porous structure activated carbon with a large surface. 85 According to the study of Luo et al , 86 porous activated carbon from balsa wood ultra-low-density biomass was prepared by one-step phosphoric acid activation at different impregnation ratios. The phosphoric acid activation process can effectively control the surface area and pore size distribution of balsa active materials.…”

Globally, environmental and energy conservation concerns have sparked a push for more efficient and long-term energy sources. Researchers worldwide have put significant effort into developing supercapacitor-based energy storage devices by fabricating electrode materials from affordable porous carbon. The advantages of porous carbons are low-cost processes, high porosity, high surface area, facilitation of surface modification, high conductivity, high mechanical stability, high chemical stability, facilitation of fast ion transport, high rate capability, and high specific capacitance. Using them as electrodes in supercapacitors (SCs) may lead to better performance in specific capacitance and long-term cyclic stability. This study focuses on the recent development of electrode materials for SCs using porous carbons obtained from several diverse sources, such as biomass, polymers, lignite, metal salts, melamine, etc. Therefore, the topic of this review is the most current development of electrode materials for SCs applications. SCs were subjected to a battery of electrochemical tests, which focused on their performance from a crucial perspective, concentrating on the porous carbon’s surface area and surface functional groups. The report also highlights the supercapacitor’s prospects and challenges.
