Preparation method of powder embedding aluminizing-laser shock strengthening zinc ion battery negative electrode material

The invention belongs to the technical field of zinc ion battery negative electrode materials, and discloses a preparation method of a powder-embedded aluminizing-laser shock strengthening zinc ion battery negative electrode material. The aluminum element is infiltrated into the surface and the interior of the zinc foil through powder embedding aluminizing-laser shock strengthening, so that a zinc-aluminum alloy is formed on the surface of the zinc foil, and a more active aluminum metal layer in an alloy layer can form an Al2O3 protective layer in situ in the cycle process of the battery, so that uniform deposition of metal zinc is effectively promoted, the influence of an inert byproduct ZnO or Zn (OH) 2 is reduced, and the growth of zinc dendrites is inhibited. The method is simple to operate, can be applied on a large scale, and can inhibit passivation of zinc metal and prolong the cycle life of the aqueous zinc ion battery. 本发明属于锌离子电池负极材料的技术领域，公开了一种粉末包埋渗铝-激光冲击强化锌离子电池负极材料的制备方法。通过粉末包埋渗铝-激光冲击强化将铝元素渗入到锌箔表面和内部
