Nitrogen‐Doped Graphene Aerogels for Supercapacitors: Advances in Synthesis and Electrochemical Performance
University of Technology Malaysia · Technical University of Malaysia Malacca
Abstract
ABSTRACT Nitrogen‐doped graphene aerogels (NGAs) have attracted much attention as next‐generation electrode materials for supercapacitors because of their high surface area, excellent conductivity, and chemical tunability. Recent studies have confirmed how nitrogen doping can improve pseudocapacitive behaviour, wettability, and electron transport, thus significantly improving the specific capacitance, energy density, and cycling performance. This review analyses the different synthesis strategies, such as hydrothermal self‐assembly, sol‐gel polymerisation, and template‐directed synthesis, and shows the electrochemical performance obtained from both symmetric and asymmetric set‐ups. The best‐performing NGAs…
