摘　　要：Aqueous zinc-ion batteries provide a most promising alternative to the existing lithium-ion batteries due to their high theoretical capacity,intrinsic safety,and low cost.However,commercializing aqueous zinc-ion batteries suffer from dendritic growth and side reactions on the surface of metallic zinc,resulting in poor reversibility.To overcome this critical challenge,here,we report a one-step ultrafast laser processing method for fabricating three-dimensional micro-/nanostructures on zinc anodes to optimize zinc nucleation and deposition processes.It is demonstrated that the three-dimensional micro-/nanostructure with increased specific surface area significantly reduces nucleation overpotential,as well as preferentially absorbs zinc ions to prevent dendritic protuberances and corrosion.As a result,the presence of threedimensional micro-/nanostructures on the zinc metal delivers stable zinc plating/stripping beyond 2500 h(2 mA cm-2/1 mAh cm-2)in symmetric cells,a high Coulombic efficiency(99.71%)in half cells,and moreover an improved capacity retention(71.8%)is also observed in full cells.Equally intriguingly,the pouch cell with three-dimensional micro-/nanostructures can operate across various bending states without severely compromising performance.This work provides an effective strategy to construct ultrafine and high-precision three-dimensional micro-/nanostructures achieving highperformance zinc metal anodes and is expected to be of immediate benefit to other metal-based electrodes.
