  text: Rechargeable aqueous Zn-ion energy storage devices are promising candidates
    for next-generation energy storage technologies. However, the lack of highly reversible
    Zn2+-storage anode materials with low potential windows remains a primary concern.
    Here, we report a two-dimensional polyarylimide covalent organic framework (PI-COF)
    anode with high-kinetics Zn2+-storage capability. The well-organized pore channels
    of PI-COF allow the high accessibility of the build-in redox-active carbonyl groups
    and efficient ion diffusion with a low energy barrier. The constructed PI-COF
    anode exhibits a specific capacity (332 C g–1 or 92 mAh g–1 at 0.7 A g–1), a high
    rate capability (79.8% at 7 A g–1), and a long cycle life (85% over 4000 cycles).
    In situ Raman investigation and first-principle calculations clarify the two-step
    Zn2+-storage mechanism, in which imide carbonyl groups reversibly form negatively
    charged enolates. Dendrite-free full Zn-ion devices are fabricated by coupling
    PI-COF anodes with MnO2 cathodes, delivering excellent energy densities (23.9
    ∼ 66.5 Wh kg–1) and supercapacitor-level power densities (133 ∼ 4782 W kg–1).
    This study demonstrates the feasibility of covalent organic framework as Zn2+-storage
    anodes and shows a promising prospect for constructing reliable aqueous energy
    storage devices.
