Abstract:

Lithium-ion batteries (LIBs) have been widely used in the field of energy storage due to their advantages of mature technology, high energy density and long service life. However, due to the limitation of electrode materials and electrolytes, traditional commercial LIBs have the disadvantages of limited reversible specific capacity, low power density, poor cycle performance, high cost of production materials and potential safety hazards in the working process. In this paper, covalent organic frameworks (COFs), a crystalline organic porous material composed of light elements, were briefly described. Its ordered large pores, pre-designed structure, large specific surface area, low density, easy functionalization and other advantages fully had the potential to be used as key materials for LIBs. Various COFs designed by researchers in recent years and their applications in LIBs were reviewed, including the application of COFs in LIBs electrode materials, separators and electrolytes. It was concluded that COFs had excellent electrochemical properties when applied to LIBs, Finally. the research direction of COFs in LIBs was predicted in order to provide some reference for the development of energy storage and renewable energy industries.

Key words: covalent organic framework, porous material, lithium-ion battery, performance, renewable energy, safety

摘要:

锂离子电池(LIBs)具技术成熟、能量密度较高、使用寿命长等优点使其在储能领域研究应用广泛,但传统商业化LIBs由于本身电极材料及电解质的限制,存在可逆比容量有限、功率密度不高、循环性能较差、生产材料成本较高、工作过程面临安全隐患等不足。本文简述了由轻质元素构成的晶态有机多孔材料共价有机框架(covalent organic frameworks,COFs),其有序的大孔道、可预先设计的结构、较大比表面积、低密度、易功能化等优势,完全具备利用于LIBs关键材料的潜力。回顾了近年来研究者们设计的各种COFs及其在LIBs的应用,包括COFs在LIBs电极材料、隔膜、电解质中的应用,得出COFs应用于LIBs具有卓越的电化学性能,最后对其在LIBs的研究方向给予预测,以期为储能和再生能源产业的发展提供一定参考。
