Abstract

With the rapid development of renewable energy, lithium-ion batteries have garnered significant attention. The anode material is one of the key factors determining the performance of lithium-ion batteries. Silicon anodes, due to their exceptionally high specific capacity and abundant reserves, are widely regarded as a promising alternative anode material. However, silicon anodes currently face challenges such as volume expansion and unstable SEI films, which lead to reduced cycling stability. This paper summarizes the improvements in the electrochemical performance of silicon anodes through nano structuring, including various preparation methods and the effects of materials of different dimensions on cycling stability. Research has found that nanomaterials of different dimensions can mitigate volume expansion to some extent, shorten lithium-ion diffusion paths, and enhance the conductivity of silicon anodes. The significance of this paper lies in providing a theoretical basis and research direction for the further development of higher-performance silicon anode materials, thereby advancing the progress of batteries and renewable energy.
