## Description

- description: 'Recently, aqueous rechargeable zinc-ion batteries (AZIBs) have attracted
    much attention owing to their low cost and intrinsic safety. However, the reversibility
    of AZIBs is limited by dendrite growth on the Zn anode, which leads to low Coulombic
    efficiency and potential short circuit during cycling. Herein, we develop a new
    strategy using electrostatic shielding to enable a highly reversible Zn anode.
    Specifically, a cationic polymeric ionic liquid (PIL) coating layer with a strong
    positive charge evens out the charge distribution on the surface of the Zn electrode,
    enabling uniform stripping and deposition of Zn. As a result, a symmetric Zn-Zn
    cell can sustain stripping-plating for over 2000 h at 1 mA cm-2 with a capacity
    limit of 1 mAh cm-2, far exceeding the performance of bare Zn electrode. A highly
    reversible Zn stripping-plating on Cu substrate is also achieved with an average
    coulombic efficiency of 99.5% over 1100 cycles. PILZ layer can even allow a uniform
    Zn deposition of up to 30 m thick, allowing large utilization of the Zn foil.
    Moreover, the coating layer enables the stable cycling of a MnO2-Zn full cell
    with a high areal capacity of 1 mAh cm-2.  '
