Abstract

In recent years, silicon-based materials have attracted a lot of research attention due to their high theoretical capacity, especially when applied as the anode materials of lithium ion batteries. In this paper, Si/C composite is prepared using a simple high-energy ball milling method, and the products with different milling time and carbon sources are compared. The Si/C composite material demonstrates excellent electrochemical performance when used as the anode of the lithium ion batteries. Moreover, the carbon in the product can effectively accommodate the volume expansion of the anode during the insertion and desertion of lithium ions. It is believed that the facile ball milling method, which synthesizes the silicon-based materials and which demonstrates good electrochemical performance, is beneficially deployed in the application of lithium ion batteries.

Key words： lithium-ion batteries; silicon/carbon composite; anode
