摘要

Supercapacitors have garnered significant attention worldwide due to their unique abilities, including high power density, long cycle life, and environmental friendliness. They act as a critical link bridging the energy–power gap between conventional capacitors and batteries. In recent years, extensive research has been carried out on developing advanced electrode materials to enhance the electrochemical performance of supercapacitors. This review paper highlights research progress in various electrode materials, including metal oxides/hydroxides, carbon-based materials, MXenes, and their composites. The different parameters governing the electrochemical performance of electrodes, such as specific surface area, morphology, porosity, electrical conductivity, and redox kinetics, have been comprehensively reviewed with critical examples. This article explores the latest advancements in electrode materials for next-generation supercapacitors.
