Covalent organic frameworks (COFs) are two or three dimensional structures with strong, covalent bonds between organic components to afford porous, stable, and crystalline materials. In this talk, I will present a facile self-assembling method of COFs films for zinc aqueous batteries with excellent capacity retention. The ultrathin COF film was fabricated via the scalable dip-coating of the organic precursors. The nanoporous and mechanically flexible COF film coated onto the Zn electrodes successfully permit efficient mass and charge transport of zinc aqueous batteries while suppressing surface corrosion and growth of large Zn dendrites. This work provides a straightforward way of addressing the chronic issue of surface corrosion and formation of large Zn dendrites in zinc aqueous batteries to potentially improve the performance of metal anodes with the extension to Li, Na, and K in other rechargeable energy storage systems. |
