“…It has been discussed that COFs and ZnO quantum dots (QDs) combined by covalent bonds are applied as anode materials for the zinc–nickel batteries. [ 138 ] The prepared COFs provide an efficient channel for ion transport, regulating the concentration gradient of Zn(OH) 4 2− , thus slowing down deformation and dendrite growth. Small‐sized QDs have large specific surface area, which can completely contact with electrolyte, facilitating the electrochemical reaction.…”

Zinc–based batteries (ZBBs) have demonstrated considerable potential among secondary batteries, attributing to their advantages including good safety, environmental friendliness, and high energy density. However, ZBBs still suffer from issues such as the formation of zinc dendrites, occurrence of side reactions, retardation of reaction kinetics, and shuttle effects, posing a great challenge for practical applications. As promising porous materials, covalent organic frameworks (COFs) and their derivatives have rigid skeletons, ordered structures, and permanent porosity, which endow them with great potential for application in ZBBs. This review, therefore, provides a systematic overview detailing on COFs structure pertaining to electrochemical performance of ZBBs, following an in–depth discussion of the challenges faced by ZBBs, which includes dendrites and side reactions at the anode, as well as dissolution, structural change, slow kinetics and shuttle effect at the cathode. Then, the structural advantages of COF–correlated materials and their roles in various ZBBs are highlighted. Finally, the challenges in the application of COF–correlated materials in ZBBs are outlined and an outlook on the future development of COF–correlated materials for using in ZBBs is provided. The review would serve as a valuable reference for further research into the utilization of COF–correlated materials in ZBBs.This article is protected by copyright. All rights reserved

Energy storage technologies are eminently developed to address renewable energy utilization efficiently. Porous framework materials possess high surface area and pore volume, allowing for efficient ion transportation and storage. Their unique structure facilitates fast electron transfer, leading to improved battery kinetics. Porous organic framework materials like metal–organic (MOF) and covalent organic (COF) frameworks have immense potential in enhancing the charge/discharge performances of aqueous Zn–alkaline batteries. Organic frameworks and their derivatives can be modified feasibly to exhibit significant chemical stability, enabling them to tolerate the harsh battery environment. Zn–alkaline batteries can achieve enhanced energy density, longer lifespan, and improved rechargeability by incorporating MOFs and COFs, such as electrodes, separators, or electrolyte additives, into the battery architecture. The present review highlights the significant electrode design strategies based on porous framework materials for aqueous Zn–alkaline batteries, such as Zn–Ni, Zn–Mn, Zn–air, and Zn–N2/NO3 batteries. Besides, the discussion on the issues faced by the Zn anode and the essential anode design strategies to solve the issues are also included.
