Si anode materials are essential for the realization of high-energy-density lithium-ion batteries due to their theoretical capacity, which is 10 times higher than that of graphite-based anode materials, which are currently the most widely used. However, Si anode materials have low electrical conductivity, and during lithiation and de-lithiation, cracks and crushing of particles due to significant volume changes occur, resulting in the continuous formation of the solid electrolyte interphase (SEI) layer due to electrolyte decomposition reactions, which leads to a rapid decrease in capacity. To overcome these limitations, research has focused on compounding with carbon materials that can provide electrical conductivity and suppress volume expansion. In this paper, we investigate the formation of various types of Si/C composite structures using hydrocarbons as carbon sources and the resulting improvement in electrochemical properties.
