Lithium-ion batteries play an important role in dealing with the energy crisis, and their high energy density, fast charging, and discharging performance, long life, environmental protection, safety, and adaptability make them obvious advantages in the field of energy storage. The anode is an important component in lithium-ion batteries, and the selection and performance of anode materials directly affect the key indicators such as energy density, cycle life, and safety performance of the battery. As a new type of anode material, silicon-based anode material has the advantages of high specific capacity, which can greatly increase the storage capacity of the battery, and good fast-charging performance, which ensures the rapid charging and discharging of the battery. This paper firstly introduces three kinds of silicon-based anode materials with wide application potentials in many industries: nanometer Si, Si-C composite, and Si-metal composite, and then introduces three silicon anode modification strategies, namely binder, pre-lithiation, and electrolyte additives, and their application effects. Through these strategies, the advantage of the high specific capacity of silicon anode can be fully utilized, thus improving the energy density and cycle stability of lithium-ion batteries. Finally, the future applications and development directions of silicon-based materials and their modification strategies are summarized.
