The future development direction of Silicon carbide composite materials may include the following aspects:

(1) Structural optimization. The bonding force of silicon-carbon particles is weak, and they are prone to separation and peeling, resulting in a decrease in battery capacity and cycle life; therefore, one of the future development directions may be to improve the bonding force and stability of Silicon carbide composite materials through structural optimization.

(2) Material modification. By adjusting the chemical composition and structure, such as introducing porous materials and nanomaterials, the electrochemical performance and stability of the silicon-carbon negative electrode can be further improved.

(3) Developing new preparation technologies. The current preparation method is relatively complicated. It requires chemical synthesis to prepare silicon and carbon precursors, which are then mixed and formed into silicon-carbon negative electrodes through high temperature and high pressure processes; one of the future development directions may be to develop new preparation technologies, such as laser preparation and plasma preparation, to improve production efficiency and reduce costs.

(4) Expanding the application field. In addition to lithium-ion batteries, silicon-carbon negative electrodes may also be used in supercapacitors, energy storage systems and other fields; one of the future development directions may be to expand the application field of silicon-carbon negative electrodes to meet the needs of different scenarios.

(5) Standardization construction. Standards are the technical support for regulating the production, testing and application of silicon-carbon negative electrodes. Standardization construction can promote the development and application of technology, improve product quality and international competitiveness, and protect the legitimate rights and interests of producers and users. It is also one of the main development directions in the future.
