The present disclosure provides a composite material of a metal zinc foil and a zinc-philic crystal nucleus, and a preparation method and application thereof. The preparation of the composite material includes configuring a metal salt solution as a deposition solution, and then placing the metal zinc foil in the deposition solution, and obtaining by in-situ chemical deposition. The volume of the zinc-philic nuclei is smaller, and the thin nuclei can be uniformly covered on the surface of the zinc foil. This unique structure can not only effectively suppress the zinc dendrite, but also because the thickness of the nuclei covering the surface of the zinc foil is thin, It can effectively ensure that the reaction surface area of the zinc electrode is maintained to a large extent, thereby avoiding the negative impact of modification on the zinc anode material, and greatly improving the cycle performance of the battery. |
