Covalent organic frameworks for next-generation of lithium-ion batteries

Abstract

The demand to develop lithium-ion batteries (LIBs) is growing as their consumption in various applications rises. In this regard, it is very important to pay attention to materials with suitable properties for use in LIBs. The energy storage capacity, cycle life, weight, and recycling of aging batteries are expected to improve with these materials. Recently, covalent organic frameworks (COFs) have shown great promise for use in cathode, anode, electrolyte, and separators of LIBs due to their numerous properties, including porosity and excellent physical and chemical stability. This review discusses the application of COFs in the next-generation of LIBs. First of all, the Main components, working principles, and characteristics of LIBs are described. After that, the advantages, applications, and synthesis methods of COFs are discussed. Finally, the application of COFs in various parts of LIBs by key features and the associated challenges is highlighted. In this review, we focus on improving batteries by introducing and developing COFs as a new-generation of materials for energy storage applications to overcome the current limitations and provide promising alternatives for current LIBs.
