Application and Prospect of COF/MOF‐Based Composites and Their Derivatives in Sodium Batteries

Le résumé fourni par la source

Abstract Sodium, an element significantly more abundant in the Earth's crust compared to lithium, has positioned sodium‐based batteries as promising alternatives to lithium‐based systems. Despite extensive research and development, sodium‐based batteries continue to encounter a range of complex challenges: sodium‐ion batteries (SIBs) suffer from sluggish ion transport kinetics and inadequate electrode stability, while sodium–sulfur (Na–S) batteries are hindered by dendrite growth, polysulfide shuttling, and limited reversible capacity. Consequently, the development of novel materials to enhance the performance of sodium‐based batteries has emerged as a viable strategy. In this context, covalent organic frameworks (COFs) and metal‐organic frameworks (MOFs) are identified as promising porous materials, offering new opportunities for advancing sodium batteries due to their tunable pore structures, high specific surface areas, and diverse topological architectures. This review systematically elucidates the novel applications of COF/MOF materials in sodium batteries, elucidating their mechanisms for enhancing electrochemical performance from multidimensional perspectives. The objective is to furnish a theoretical foundation and innovative insights for the development of sodium batteries characterized by high energy density and long‐term cycling stability.
