摘要

Despite the merits of high specific capacity, low cost, and high safety, thepractical application of aqueous Zn metal batteries (AZMBs) is plagued bythe dendritic growth and corrosion reaction of Zn metal anodes. To solvethese issues, a Zn_3(PO_4)_2·4H_2O protective layer is in-situ constructed on Znfoil (Zn@ZnPO) by a simple hydrothermal method, avoiding the traditionalslurry-casting process. The insulating and conformable ZnPO layer improvesthe wettability of Zn@ZnPO and aqueous electrolyte via decreasing thecontact angle to 11.7o. Compared with bare Zn, the Zn@ZnPO possessesa lower desolvation activation energy of 35.25 kJ mol~(-1), indicating that theZnPO fasters the desolvation of hydrated Zn~(2+) ions and thereby amelioratestheir transport dynamics. Micro-morphology and structural characterizationshow that there are no dendrites forming on the post-cycling Zn@ZnPOanodes, and the interfacial ZnPO layer remains almost identical before andafter cycles. It can be explained that the electrochemically stable ZnPO layeracts as an ionic modulator to enable the homogeneous distribution of Zn~(2+)ions, inhibiting the growth of Zn dendrites. Benefiting from these advantages,the Zn@ZnPO based symmetric and full cells deliver highly reversible Znplating/stripping behavior and long cycling lifespans.
