The invention discloses a silicon silver carbon nano hybrid material and a preparation method and application thereof. The silicon silver carbon nano hybrid material is prepared by distributing silicon nanoparticles and ultra small silver nanoparticles in a continuous carbon matrix, and the size of the silver nanoparticles ranges from 1nm to 5nm. The material is prepared by dissolving a silver salt in epoxy resin curing agent polyamine by ultrasonic method, and then curing and calcining. The continuous carbon matrix prepared by the invention can effectively restrain the volume effect of silicon in the circulation process, through technical modification in experiments, the ultra small silver nanoparticles are introduced into a silicon and carbon negative electrode, the ultra small silver nanoparticles are conducive to the formation of more emission electric fields in the process of charge and discharge, a high-speed conductive channel can be formed, and the rate performance of the silicon based negative electrode is greatly improved.
