Aqueous Zn-based batteries deliver thousands of cycles at high rates but poor recyclability at low rates. Herein, we reveal that this illogical phenomenon is attributed to the reconstructed electrode/electrolyte interface at high rates, wherein the condensed electrical double layer (EDL) and the tightly absorbed Zn ions on the Zn electrode surface afford compact and corrosion-resistant Zn deposits.
水系锌基电池在高倍率下可实现数千次循环，但在低倍率下的循环性能较差。在此，我们揭示了这种不合逻辑的现象归因于高倍率下重建的电极/电解质界面，其中，凝聚的双电层（EDL）和紧密吸附在锌电极表面的锌离子形成了致密且耐腐蚀的锌沉积物。
