The preparation method includes the following steps: S1. dissolving a graphite anode powder in an acid solution, and conducting solid-liquid separation (SLS) to obtain a precipitate; and washing and drying the precipitate, adding a reducing agent, and subjecting a resulting mixture to heat treatment to obtain a purified graphite material; and S2. mixing a modified silicon powder with the graphite material, adding a resulting mixture to a polyimide (PI)-containing N,N-dimethylformamide (DMF) solution, and stirring; and subjecting a resulting mixture to distillation and then to carbonization to obtain the silicon/carbon composite anode material.",
