“…Similarly, those values of HEA-NP@MOL/HCPC-2.0 are closest to 90°and À 1, respectively, suggesting that it is closer to the ideal capacitor. [60][61][62] In addition, the slope of line at the low frequency, reflecting the diffusion impedance associated with the solid state diffusion of cations into intra-particle pores, are consistent with BET results.…”

High‐entropy alloy nanoparticles with a thin metal oxide layer, deposited onto hypercrosslinked polymer‐based carbon (HCPC), were synthesized through the adsorption of five metal ions in the hypercrosslinked polymers and subsequent in situ reduction of such ions (Fe2+, Co2+, Ni2+, Cu2+ and Sn2+), followed by a carbonization process. The as‐prepared composites exhibit an excellent specific capacitance (495.4 F/g at 0.5 A/g in 1 M KOH), a superior cycling stability (94.7 % of initial capacitance after 15000 cycles at 10 A/g), and ultrafast charge transport kinetics (88.9 % fast kinetic capacitance at 200 mV/s). These excellent electrochemical behaviors are attributed to the pseudocapacitance of the metal oxide layer spontaneously formed on the outermost surface of the composite, having a thickness at the nanometer scale. Such findings suggest that this simple strategy, combining multimetallic nanoparticles with porous carbon materials, has promising potential to improve specific capacitance and paves the way to develop both the preparation of high‐entropy alloys and supercapacitors with improved performance.

“…In this method, the electrodes are dipped in the electrolyte. Electric double layers form at the interface surfaces between electrodes and electrolyte, which are accessible to ions present in the electrolyte . The characterization experiments were conducted in a three‐electrode system with a Pt coil as counter electrode and an SCE as reference electrode in 1 M KCl solution.…”

Summary Tin oxide (SnO2) nanorod (NR)‐fabricated composite capacitors have been developed by vacuum‐assisted resin transfer molding process. The NRs were synthesized on carbon fiber by following hydrothermal synthesis method. Such SnO2 grown woven carbon fiber (WCF) capacitor that contains structural and energy storage functions saves system weight and volume; hence, it could offer benefits to electric vehicle, aerospace, and portable electric device industries. The SnO2‐WCF was considered as electrode and exhibited enhanced surface area relative to bare WCF. Energy storage performances of SnO2‐WCF capacitors were characterized by cyclic voltammetry, galvanostatic charge‐discharge, and electrochemical impedance spectroscopy measurements, and improved specific capacitance (0.148 F/g), energy density (15.06 mWh/kg), and power density (1.16 W/kg) were achieved at 30 mM of SnO2 concentration. Hence, this study shows that the growth of SnO2 NRs on WCF surfaces offers accessible surface area for electric charge and presented potential application of SnO2‐WCF composites to energy storage industries.
