摘　　要：传统钠离子电池常使用液体有机电解质,存在热失控等安全问题。而固态电解质具有高安全性和高能量密度,因而成为下一代储能设备材料最有潜力的候选者。金属有机骨架(MOFs)由金属节点和有机连接器构成,具有高孔隙率、高比表面积和有序孔道,是设计快速离子导电材料的一个很有前途的结构平台。基于MOFs结构的多样性和可修饰性,介绍几种导钠离子MOFs基固体电解质的研究设计,包括引入掺杂相应阴离子钠盐的离子液体或有机溶剂、钠化处理、枝接与电解质离子相互作用的官能团和与聚合物复合的杂化材料。Traditional sodium-ion batteries often use liquid organic electrolyte,which has safety problems such as thermal runaway.The high safety and high energy density of solid electrolyte make it the most potential candidate for the next-generation of energy storage equipment materials.The metal-organic frameworks(MOFs),composed of metal nodes and organic connectors,has high porosity,high specific surface area and ordered pores,and are a promising structural platform for the design of fast ionic conductive materials.Based on the diversity and modifiability of MOF structure,this review introduced the research and design of several sodium-conducting MOFs-based solid electrolytes,including the introduction of ionic liquids or organic solvents doped with corresponding anionic sodium salts,sodium treatment,grafting functional groups interacted with electrolyte ions and hybrid materials compounded with polymers.
