摘要

Inexpensive and abundant sodium resources make energy storage systems using sodium chemistry promising replacements for typical lithium-ion rechargeable batteries (LIBs).Fortuitously,aqueous sodium-ion rechargeable batteries (ASIBs),which operate in aqueous electrolytes,are cheaper,safer,and more ionically conductive than batteries that operate in conventional organic electrolytes;furthermore,they are suitable for grid-scale energy storage applications.As electrode materials for storing Na+ ions in ASIBs,a variety of multifunctional metal-organic frameworks (MOFs) have demonstrated great potential in terms of having porous 3D crystal structures,compatibility with aqueous solutions,long cycle lives (≥1000 cycles),and ease of synthesis.The present review describes MOF-derived technologies for the successful application of MOFs to ASIBs and suggests future challenges in this area of research based on the current understanding.
