固态电池狂拉碳酸锂需求

Core Viewpoint - The global solid-state battery industry is accelerating its development, with sulfide solid electrolytes emerging as the primary focus due to their superior mechanical processing capabilities and ionic conductivity [2]. Group 1: Industry Development - Since 2025, numerous automotive and battery companies, including CATL, BYD, Toyota, Panasonic, Samsung SDI, LG, and SK On, are advancing the sulfide technology route for all-solid-state batteries, with most companies planning to install them in vehicles between 2027 and 2028, and mass production expected after 2030 [3]. Group 2: Demand and Consumption - By 2030, the global demand for solid-state batteries is projected to reach 195.6 GWh, representing an increase of nearly 16 times compared to 2025. The consumption of lithium carbonate due to solid-state batteries is expected to be significantly higher than that of traditional liquid electrolyte batteries, with a projected demand of approximately 322-353 tons of lithium carbonate per GWh of lithium phosphorous sulfide chloride solid-state battery [4]. - The consumption of lithium carbonate is expected to increase by over 50% compared to traditional liquid lithium batteries, even without considering the impact of metallic lithium anodes [4]. Group 3: Technological Challenges and Innovations - Currently, the technology for metallic lithium anodes has not fully resolved dendrite issues, and existing technologies primarily exhibit lithium in alloy forms rather than pure lithium. Innovations such as lithium-carbon alloys and lithium composite technologies are being developed to address these challenges [6]. - The actual demand for lithium carbonate driven by metallic lithium anodes is estimated to be in the range of 100-150 tons, and when combined with the benefits of sulfide solid electrolytes, the single consumption of lithium carbonate in sulfide solid-state batteries is expected to increase by 70%-80% compared to traditional liquid lithium batteries [6].
