Aqueous Zn-ion batteries (ZIBs) have garnered significant interest as an important solution for large-scale energy storage due to their enhanced safety and affordability. Nevertheless, dendrites formation and side reactions faced by Zn anodes have hindered their commercial development. Electrolyte additives, among various methods to stabilize Zn anodes, have emerged as the most commercially viable technique due to their low dosage and potent effects, offering substantial economic benefits. While massive literature reviews have explored strategies for comprehensive Zn anode stabilization, there...

Aqueous zinc-ion batteries (ZIBs) enjoy a good reputation for being safe, affordable to produce, and ecologically friendly due to the use of water-based electrolytes. The main factors restricting the development of ZIBs, however, are the negative effects of dendrite deposition on the zinc anode and the dissolution of common cathodes such as Mn and V-based cathodes. Various techniques have been used to address these issues, including regulating the electrolyte concentration or solvation structure, developing a coating or current collector to lessen anode dendrite growth, and improving the struc...

Metallic Zn has been regarded as ideal anodes in aqueous electrolyte owing to its high theoretical capacity, intrinsic safety, low cost, and nontoxicity. However, the Zn dendrite growth and the side-reactions hindered the practical application of Zn anode. Herein, a thin and uniform three-dimensional (3D) COOH-functionalized covalent organic frameworks (COF) film (denoted as 3D-COOH-COF) is designed and in-situ synthesized as a protective layer to stabilize the Zn anode. The thin 3D-COOH-COF protection film with abundant negative functional groups and homogeneous nanochannels facilitates the f...
