The aqueous zinc-ion batteries (AZIBs) exhibit promising potential as a viable solution for large energy storage. Solving dendrite growth the surface of zinc metal anode in AZIBs is of great significance for its application in energy storage field. Among the many strategies for solving the zinc anode problem, the influence of zinc anode pretreatment is often ignored. The effect of sandpaper physical polishing on the performance of zinc anode was studied in this paper. The striated grooves formed on the surface of the zinc anode after sandpaper treatment make the zinc anode have a large specific surface area and a high zinc plating/stripping kinetics. It was found that sandpaper with larger mesh count (the finer the sandpaper) could reduce roughness and had the higher the electrochemical performance of zinc anodes. Consequently, the cycle life of 2000 M-Zn symmetric battery can reach 900 h under the current density of 0.5 mA cm⁻². In the application of energy storage, the full battery composed of 2000 M-Zn and sodium doped V₂O₅ cathode (NVO) still has a specific capacity of 148.6 mAh g⁻¹ after 500 cycles, and has a stable rate performance. The pretreatment strategy of zinc anode holds significant importance in the applications of AZIBs.

水性锌离子电池（AZIB）作为大型储能的可行解决方案展现出巨大的潜力。解决AZIBs中锌金属负极表面的枝晶生长问题对其在储能领域的应用具有重要意义。在解决锌阳极问题的众多策略中，锌阳极预处理的影响常常被忽视。研究了砂纸物理抛光对锌阳极性能的影响。砂纸处理后锌阳极表面形成的条纹沟槽使锌阳极具有较大的比表面积和较高的镀/剥锌动力学。结果发现，砂纸目数越大（砂纸越细），可以降低粗糙度，锌阳极的电化学性能越高。^{因此，2000 M-Zn对称电池在0.5 mA cm -2}的电流密度下循环寿命可达900 h。在储能应用中，由2000M-Zn和钠掺杂V₂O₅^-1的比容量，并且具有稳定的倍率性能。锌阳极的预处理策略在AZIBs的应用中具有重要意义。
