Highly Ordered Silicon/Carbon Composite Materials Based on Biomass and Their Application in Lithium Batteries

With the rapid development of electric vehicles and mobile devices, the performance and safety of energy storage and conversion devices mainly with lithium-ion batteries have been paid attention to. Negative electrode material is an important component of lithium-ion battery, which has an important influence on the overall performance of the battery. In recent years, the research of highly ordered silicon / carbon composites as the negative electrode has been significantly developed. Highly ordered silicon / carbon composites have great potential to increase the energy density of lithium-ion batteries and improve the battery performance with the characteristics of high capacity, low cost and environmental friendliness. In this paper, the application of highly ordered silicon / carbon composites in lithium-ion batteries is expected to provide reference to relevant personnel.
