The invention belongs to the technical fields of nanocomposite material and lithium ion battery, and relates to a bicontinuous-structural composite material and a preparation method and an application thereof in a lithium ion battery negative electrode. The problems are solved by selecting two ways. On one hand, silicon having rich pores is used in design of a silicon material morphology; the existence of the pores can increase the specific surface area of the silicon material, and increases the contact area of the silicon material with an electrolyte solution so as to reduce the transmission distance of lithium ions; and in addition, the existence of the pores can relieve huge volume change during lithium de-intercalation of a carbon material, and improves the cycle performance. On the other hand, the silicon material is composited with a material having good electronic conductivity, and the continuous dual-phase silicon composite material is prepared. The bicontinuous-structural composite material not only can overcome damage on a battery due to huge volume change of the silicon material, but also improves the electronic conductivity of the material.
