The silicon-based anode in lithium-ion battery

Abstract

Lithium-ion batteries are now widely used in our society. Developing advanced anode material to improve the property of Lithium-ion batteries has aroused more and more attention in recent years. The silicon-based material is one of the most popular materials for the anode owning to the unique advantages of theoretically high capacity, low operating point, rich material resources, and environmental friendliness. However, the decay of capacity fading during the cycling resulting from huge volume change and poor conductivity of this kind of anode material significantly limited the applications. Thus, novel strategies need to be developed urgent. For this scope, the silicon-based components with different materials and structures have been developed. Here we summarized a series of silicon-based components, involving in oxide composite materials, silicon/metal oxide composite materials, Si/Carbon nanotubes composite materials, and graphene composite material, from the aspects of the preparation process, microstructure, and performance of these silicon-based anode materials.
