Published: Aug. 1, 2024

Abstract Supercapacitors have become attractive energy storage devices due to their high power density, good cycling stability, and fast charging discharging speeds. Porous carbon has great specific surface area, density conversion performance, so porous as supercapacitor electrode material been widely concerned. Carbon materials with different dimensions sizes, such spheres, nanotubes, nanofibers graphene activated can provide performance advantages. At the same time, composite of metal compounds, conductive polymers particles containing N/P/O/S further optimize materials, well significant effects on increase area are obtained. This article introduces used in recent years, multi-level structural related materials. We first introduced compared electrochemical performance. Then, based various research results, factors affecting its were discussed detail. As as, preparation methods introduced, requirements, advantages disadvantages briefly analyzed. The application combined other supercapacitors is listed. Finally, a summary outlook current status supplied, providing reference for rational design future.

Selective Nitrogen Doping at Hole Edges of Holey Graphene: Enhancing Ionic Transport Mechanisms for High‐Performance Supercapacitors

Small Methods, Journal Year: 2025, Volume and Issue: unknown

Published: March 24, 2025

Abstract Developing highly holey graphene with controllable doping enhances ionic transport and conductivity, boosting the performance of energy storage devices like supercapacitors. However, method for precise site‐selective effects heterogeneous atomic at pore edges on ion remain not fully understood. This study presents a to achieve precisely selectively high nitrogen (N‐doping) hole porous (N‐EHG) through two‐step process. Compared untreated (HG) basal plane‐doped (N‐BHG), N‐EHG demonstrates superior charge capacity conductivity. Analyzing structure, size distribution, hydrophilicity influenced by carbon–oxygen ratio, shows specific surface area 509 m 2 g −1 , significantly higher than HG's 100 . Electrochemical results revealed that N‐BHG achieved gravimetric capacitances 482.3 624.4 F respectively, due enhanced diffusion, exceeding HG ≈12‐ 15.6‐fold. Furthermore, assembled coin‐cell retains over 99% capacitance after 15,000 cycles, demonstrating exceptional stability. Both show diffusion‐governed storage, benefitting further from edge‐state N‐doping. Density Functional Theory (DFT) calculations reveal lower barrier diffusion strong K⁺ adsorption edge pyridinic‐N, where increased electrode creates negative center N‐dopants, enhancing binding. These findings underscore potential N‐doping in advanced applications.
