Some companies are opting to retrofit existing lines to retain original equipment [1][2][10]. Key Points and Arguments - **Cost as a Core Bottleneck**: The primary bottleneck for large-scale deployment of solid-state batteries is cost. Although there have been technological breakthroughs, economic feasibility must be improved, alongside enhancements in energy density, range, and cycle life to surpass liquid batteries [1][5][11]. - **International Competitive Landscape**: Overseas companies like Samsung and Toyota have a first-mover advantage in solid-state battery technology and supply chain layout, particularly in raw materials and patent strategies. However, domestic companies have made rapid advancements in equipment manufacturing, especially in dry preparation and isostatic pressing [1][8][10]. - **Domestic Leadership**: Domestic manufacturers have become significant leaders in the global solid-state battery equipment sector, particularly in dry preparation processes and isostatic press manufacturing, boasting a complete lithium-ion battery production equipment supply chain [1][10]. - **Future Development Factors**: Key factors for the future development of solid-state batteries include improving energy density, range, and cycle life, reducing production costs, and enhancing international collaboration and patent strategies to accelerate the development of new materials and processes [1][11]. Additional Important Insights - **Production Line Investment**: The investment for small pilot lines is approximately 20 million yuan, while pilot lines require 60 to 70 million yuan, and gigawatt-hour level lines need about 200 to 300 million yuan. The investment distribution is approximately 40% for front-end equipment, 20-30% for mid-process, and lower for back-end [2][11]. - **Production Capacity Bottlenecks**: The current bottleneck in pilot production lines is primarily in the isostatic pressing stage, where domestic equipment operates at a slower speed, significantly limiting overall capacity [2][13]. - **Technology Transition**: The industry is leaning towards wet processes for mass production due to their efficiency and cost-effectiveness, despite dry processes having potential advantages in performance and stability [15][16]. - **Equipment Suppliers**: Major domestic suppliers include Manster, Singapore, and Sile, which have made adjustments to meet new safety requirements. Foreign suppliers like Germany's Bühler also provide relevant equipment, but domestic manufacturers are favored due to geographical advantages and cost control [18][30]. Conclusion The solid-state battery industry is at a pivotal point, with significant advancements in technology and production capabilities. However, challenges remain, particularly in cost reduction and performance enhancement, which are critical for achieving large-scale commercialization. The competitive landscape is evolving, with domestic manufacturers rapidly catching up to their international counterparts, particularly in equipment manufacturing.
