Emerging Two–Dimensional Intercalation Pseudocapacitive Electrodes for Supercapacitors

ChemElectroChem, Journal Year: 2024, Volume and Issue: 11(15)

Published: April 10, 2024

Abstract The growing need for efficient energy storage has spurred advancements in supercapacitors (SCs), aiming to offer high power and density simultaneously. While SCs longer cycles higher values, their low densities limit practical applications. In response, pseudocapacitive materials have emerged, leveraging reversible Faradaic reactions at or near the surface enhanced storage. This approach surpasses constraints of electrical double layer mass transfer batteries. Progress asymmetric loading improved yet maintaining without compromising remains a hurdle. Advancements pseudocapacitance through intercalation during charging/discharging processes, especially layered structures like graphite, graphene, transition metal oxides (TMOs) dichalcogenides (TMDCs), MXenes, metal–organic frameworks (MOFs) proven significant. intercalated species induce irreversible structural changes, contributing physicochemical characteristics electrode materials. Exploring mechanism bulk two‐dimensional (2D) reveals distinct differences that enhance our understanding improve electrochemical properties superior Finally, an in‐depth exploration 2D such as TMDCs MXenes underscores significance, setting benchmark future studies subsequent advancement research.
