Aqueous rechargeable zinc-ion batteries (ZIBs) are regarded as promising candidates for large-scale energy storage systems (ESSs) owing to their low cost and high safety compared to flammable lithium-ion batteries. Nevertheless, Zn metal anodes suffer from parasitic side reactions and dendrite growth due to their instability in aqueous electrolytes. In this work, we have firstly demonstrated the significance of surface properties of the Zn anodes for reliable cell operation, and successfully stabilized the Zn anodes using several polymer layers. We discover that Zn deposition morphologies are critically dependent on the surface hydrophilicity of the Zn anodes. More importantly, we have realized stabilization of enlarged Zn anodes for large-format ZIBs, which is an indispensable requisite for highly safe large-scale ESSs. This strategy provides critical guidelines for the realization of large-scale fabrication of aqueous ZIBs. |
