Application of Silicon-Carbon composite materials in the Lithium-Ion Battery Anode

The energy crisis has become a focal issue that the entire world is currently facing together. In that case, electricity, as an important renewable energy source, has become the main development target in the current technological context. With the development of electrification, mobile electrical devices, such as electric vehicles and mobile phones, have increased significantly, thereby increasing the demand for high-performance batteries, especially lithium-ion batteries. Due to their high energy density, the ability to be recharged, and broad development prospects, lithium-ion batteries have attracted much attention. The performance of lithium-ion batteries is greatly influenced by the performance of their negative electrodes. Therefore, the development of the negative electrode of lithium-ion batteries has long been on the agenda. The silicon-carbon composite negative electrode not only utilizes the strong performance of the silicon negative electrode material but also solves the common problems faced by all the silicon-based negative electrodes by adding carbon materials. Therefore, its application potential is extremely high. This paper conducts a systematic study of the characteristics and application prospects of three types of silicon-carbon composite negative electrodes based on literature research and summary. The results help lay a certain foundation for further research directions and large-scale production for lithium-ion batteries which based on silicon-carbon composite negative electrodes in the future.
