Silicon-carbon anode materials are mainly composed of silicon- and carbon-based materials, of which silicon-based materials provide high capacity and carbon-based materials provide good electrical conductivity and structural stability.
Silicon-based materials
Silicon-based materials are lithium-embedded materials characterized by high capacity, with a theoretical capacity of 4200 mAh/g. At the same time, silicon-based materials have a low potential, which can provide good electrochemical performance. However, silicon-based materials are prone to volume changes during charging and discharging, leading to problems such as structural rupture and capacity degradation.
Carbon-based materials
Carbon-based materials have good electrical conductivity, providing good electrochemical performance and structural stability. Many types of carbon-based materials exist, including graphite, non-graphite, and carbon nanotubes. Graphite has high electrical conductivity and good charging and discharging properties and is one of the most widely used carbon-based materials.

Application of silicon-carbon anode materials in lithium batteries
Improve the energy density and power density of the battery
Silicon-carbon anode materials are characterized by high capacity and can provide higher energy density. At the same time, the excellent electrochemical performance of silicon-carbon anode materials can provide faster charging and discharging speeds, thus realizing higher power density.
Improved battery cycle life and stability
Silicon-carbon anode materials have good structural and cycle stability, which can effectively improve lithium batteries' cycle life and stability. In charging and discharging, the silicon-carbon anode material can maintain a stable structure, avoiding capacity degradation and structural rupture. At the same time, the chemical stability of silicon-carbon anode materials can resist the erosion of many chemicals, thus ensuring the long life and stability of the battery.
Improvement of battery safety
The high thermal and electrical conductivity of SiC anode materials can effectively improve the safety performance of batteries. Under high temperature conditions, the silicon-carbon anode material can quickly transfer the heat to the surrounding environment, avoiding battery failure or burning due to overheating. At the same time, the conductivity of the silicon-carbon negative electrode material is good, which can improve the battery's electrical stability and avoid the battery's explosion or fire due to short circuits and other reasons.
Application in composite electrode materials
Silicon-carbon anode materials can be compounded with other materials to prepare composite electrode materials, thereby improving the comprehensive performance of lithium batteries. For example, compounding silicon-carbon anode materials with conductive polymers, carbon nanotubes, graphene, and other materials can further improve the conductivity and lithium-embedded performance of the electrode materials, thus realizing more efficient charging and discharging. At the same time, compounding silicon carbon anode materials with metal oxides, sulfides, and other materials can further improve the capacity and cycle stability of the electrode materials, thus realizing longer battery life.
