As market demands have shifted and technology has advanced, the development of SiC saggers has entered a new stage. In this stage, researchers are no longer limited to improving the basic properties of materials but are exploring more advanced manufacturing processes and the application of composite materials.

• Improving Material Purity and Performance: To further enhance the performance of SiC saggers, researchers have improved raw material purification techniques, reducing impurity content and ensuring the sagger maintains excellent thermal stability even at extremely high temperatures. The application of nano-sized silicon carbide particles has significantly increased the strength and wear resistance of the saggers.
• Optimizing Forming and Sintering Processes: In terms of manufacturing processes, the introduction of automation and intelligent systems has greatly improved the production efficiency of SiC saggers. By combining cold isostatic pressing with advanced sintering techniques, the size precision, density control, and internal uniformity of the saggers have reached new heights. These technological innovations have not only improved product quality but also significantly reduced production costs.
• Exploring Composite Materials: To meet more stringent processing conditions, researchers have begun exploring the combination of silicon carbide with other high-performance materials to develop multifunctional composite saggers. These composite saggers not only retain the high-temperature stability of SiC but can also provide additional chemical stability or mechanical strength under specific conditions, meeting more diversified production needs.

3. Future Research Directions: Moving Toward Broader Application Prospects

Looking ahead, the development of SiC saggers will continue to focus on higher performance and broader applications.

• Meeting Extreme Processing Conditions: As lithium battery technology continues to make breakthroughs, the requirements for materials are becoming increasingly stringent. Future research on SiC saggers will focus on handling even higher temperatures, faster thermal cycling, and more complex chemical environments. For example, developing more durable and corrosion-resistant SiC composite materials to meet the needs of solid-state battery production.
• Intelligent Manufacturing and Application: In the context of Industry 4.0, the manufacturing of SiC saggers will become more intelligent and customized. By integrating technologies such as IoT, big data, and AI, the production process of SiC saggers will achieve more precise control and optimization. Meanwhile, the use of intelligent inspection devices will ensure stricter quality control, providing a solid foundation for stable lithium battery production.
• Green and Sustainable Development: With the growing emphasis on environmental protection, future research on SiC saggers will also focus on material recycling and environmental performance. By developing renewable composite materials and more efficient recycling technologies, SiC saggers will offer more environmentally friendly solutions for lithium battery production, reducing resource waste and environmental pollution.
