Global energy consumption is increasing yearly, yet the world is trying to move toward carbon neutrality to mitigate global warming. More research is being done on energy storage devices to advance these efforts. One well-known and widely studied technology is Zn-ion batteries (ZIBs). Therefore, this paper demonstrates how laser irradiation at wavelengths of 266 and 1064 nm, in the presence of air or water, can enhance the electrochemical performance of metallic zinc anode in alkaline electrolyte. The obtained samples are characterized using X-ray diffraction analysis, scanning electron microscopy, and Raman spectroscopy. Then, the electrochemical properties are studied by cyclic voltammetry and impedance measurements. Results indicate that the laser processing of the Zn sample increases surface-specific capacity by up to 30% compared to the non-irradiated Zn sample. Furthermore, electrochemical measurements reveal enhanced participation of metallic Zn grains in the oxidation and reduction processes in irradiated samples. In future research, integrating laser treatment into electrode preparation processes can become essential for optimizing anode battery materials.
全球能源消耗逐年增加，但世界正努力朝着碳中和迈进以缓解全球变暖。为推进这些努力，人们对储能设备开展了更多研究。一种广为人知且被广泛研究的技术是锌离子电池（ZIBs）。因此，本文展示了在空气或水存在的情况下，波长为266和1064纳米的激光辐照如何能够增强碱性电解质中金属锌阳极的电化学性能。使用X射线衍射分析、扫描电子显微镜和拉曼光谱对所得样品进行表征。然后，通过循环伏安法和阻抗测量研究其电化学性质。结果表明，与未辐照的锌样品相比，锌样品的激光处理使比表面积容量提高了30%。此外，电化学测量结果表明，辐照样品中金属锌颗粒在氧化和还原过程中的参与度有所增强。在未来的研究中，将激光处理整合到电极制备过程中对于优化阳极电池材料可能至关重要。
