Applications and challenges of reaction-sintered silicon carbide ceramics in the lithium battery ind

As the global energy structure transforms towards cleanliness and low-carbonization, the lithium battery industry, as a core industry in the new energy field, has an increasing demand for high-performance materials. Silicon carbide (SiC) ceramic which with excellent high temperature resistance, high hardness, high thermal conductivity, and good chemical stability is mainly used in the lithium battery manufacturing process. 
Reaction bonded silicon carbide (RBSiC) is one of the key materials in lithium battery industry. The main features of reaction sintered silicon carbide include:high bending strength and good wear resistance, suitable for high load conditions, high thermal conductivity, acid and alkali corrosion resistance.
Application of reaction sintered silicon carbide in lithium battery industry
1.Sintering of lithium battery positive and negative electrode materials
2 .Lithium battery slurry mixing and coating
3 .Lithium battery pole piece rolling
Challenges:
1.Compared with ceramics such as alumina and silicon nitride, SiC raw materials and processing costs are higher, and production costs need to be further reduced.
2. Photovoltaic and lithium battery equipment require extremely high dimensional accuracy of SiC components, and efficient precision processing technologies (such as laser processing and ultrasonic processing) need to be developed.
Future development trends
1.Develop new sintering processes (such as microwave sintering, flash sintering) to reduce energy consumption and costs.
2.Explore SiC-graphite and SiC-carbon fiber composite materials to meet higher performance requirements.
3.Combined with 3D printing technology, rapid prototyping of SiC components with complex structures is achieved.
