Summary of Solid-State Battery Industry Conference Industry Overview - The conference focused on the solid-state battery industry, particularly the advancements and challenges faced by various companies in this field, including CATL, BYD, SAIC, NIO, and Geely [1][2][4]. Key Points and Arguments - **Government Funding**: The Ministry of Industry and Information Technology (MIIT) launched a 6 billion RMB special fund to support solid-state battery research, with CATL receiving nearly half of the funding, approximately over 2 billion RMB [2][3]. - **Research Focus**: Solid-state battery technology is still in the laboratory stage, with companies exploring different material combinations, particularly focusing on sulfide routes due to their higher ionic conductivity [1][4][6]. - **Technical Challenges**: The solid-liquid hybrid route faces issues such as low conductivity and poor interface contact. Sulfide solid electrolytes have higher conductivity but come with safety risks, including the generation of toxic hydrogen sulfide gas [1][7][10]. - **Product Development**: SAIC's Zhiji L6 model uses a semi-solid-state solution with a range of 1,000 km, but it has not fully met performance standards in terms of rate and puncture tests due to the presence of electrolyte [9][14]. - **Manufacturing Process**: The final manufacturing process for solid-state batteries includes steps like dry coating, dry mixing, and densification. The dry process is expected to be widely applicable across various lithium-ion batteries once matured [16][18]. - **Market Demand**: There is a growing demand for higher energy density while maintaining good cycle life and rate performance. Current semi-solid-state technology has limited improvements in energy density compared to traditional liquid technologies [14][13]. Additional Important Insights - **Material Routes**: While sulfide routes dominate current research, oxide routes are also being explored for their thermal stability and broader operating temperature range, although they currently receive less focus [6][10]. - **Cost Considerations**: The cost of semi-solid sulfide technology is comparable to CATL's NCM811 products, but the bill of materials (BOM) cost is approximately 7% higher, limiting large-scale applications in power and energy storage [12][13]. - **Safety Concerns**: The industry is increasingly focused on safety, with major manufacturers like CATL and BYD aiming for long-term goals through the development of solid-state sulfide products [8][10]. - **Future Prospects**: The next three years are expected to see no full solid-state projects, with the market primarily focusing on semi-solid-state technologies. The industry is still grappling with issues related to cycle life and rate performance [14][33]. Conclusion The solid-state battery industry is at a critical juncture, with significant government support and ongoing research efforts. However, challenges related to safety, manufacturing processes, and performance metrics remain key hurdles that need to be addressed for successful commercialization.
