摘要
水系锌离子电池(AZIB)因其成本低、安全性高和环境友好等特性而备受关注.目前,AZIB正极材料主要为无机材料,其锌离子扩散动力学迟缓、库仑效率不高、循环稳定性欠佳以及环境危害性等问题,严重制约了它的应用.共价有机框架材料(COF)作为一种新型有机正极材料,以其高比表面积、高孔隙率、优异的电化学性能以及环境友好特性受到关注.本文综述了COF应用于AZIB正极中的最新研究进展,包括含羰基、含氮和其他正极材料的设计策略和性能,并探讨了当前面临的挑战和未来发展机遇.
Abstract
The aqueous zinc ion batteries(AZIB)have attracted attention due to their low cost,high safety,and environmental friendliness.Currently,the cathodes of AZIB are mainly inorganic materials,but their sluggish ionic diffusion kinetics,low Coulombic efficiency,poor cycling stability,and environmental harmfulness severely limit their practical applications.Covalent organic framework materials(COF)have gained attention as a new type of cathode materials due to their high specific surface area,high porosity,good electrochemical performance,and environmental friendliness.This review summarizes the progress of COF serving as cathode materials of AZIB,including the design strategies and performance of carbonyl-containing,nitrogen-containing and other cathodes,and also discusses the current challenges and future development opportunities.
