Description
Summary:Covalent organic frameworks (COFs) have emerged as an exciting new class of porous materials constructed by organic building blocks via dynamic covalent bonds. They have been extensively explored as potentially superior candidates for electrode materials, electrolytes, and separators, due to their tunable chemistry, tailorable structures, and well‐defined pores. These features enable rational design of targeted functionalities, facilitate the penetration of electrolytes, and enhance ion transport. This review provides an in‐depth summary of the recent progress in the development of COFs for diverse battery applications, including lithium‐ion, lithium–sulfur, sodium‐ion, potassium‐ion, lithium–CO2, zinc‐ion, zinc–air batteries, etc. This comprehensive synopsis pays particular attention to the structure and chemistry of COFs and novel strategies that have been implemented to improve battery performance. Additionally, current challenges, possible solutions, and potential future research directions on COFs for batteries are discussed, laying the groundwork for future advances for this exciting class of material. Covalent organic frameworks (COFs) are promising candidates in energy storage applications. This review summarizes the recent progress of COFs for batteries, including lithium‐ion, lithium–sulfur, sodium/potassium‐ion, lithium–CO2, and zinc‐ion/–air batteries. This review mainly focuses on the structure and chemistry of COFs and novel strategies implemented to improve battery performance along with current challenges, possible solutions, and potential future research directions.
