Western Securities(SZ:002673) Zhi Tong Cai Jing·2025-07-30 06:21Core Insights - Lithium metal anode technology is expected to be a long-term evolution direction for anode side applications, with a market potential of 12-36 billion yuan by 2030, corresponding to a lithium metal demand of 961 to 2884 tons based on a 20μm lithium metal coating [1] Application Side - Domestic leading battery manufacturers are closely following overseas companies, with mass production timelines for all-solid-state batteries generally set for 2027-2028. Notable companies like Solid Power and Factorial Energy have confirmed the use of lithium metal anodes for their next-generation solid-state batteries, while domestic players such as CATL and Qingtao Energy are leading in technology layout [2] Industry Chain - The lithium industry is driven by upstream lithium companies, with a focus on high-purity, low-cost, and safe lithium metal ingot/foil production capabilities. Companies like Ganfeng Lithium and Tianneng Technology are leading in lithium metal rolling processes. Midstream anode material manufacturers are expanding into lithium metal anodes, leveraging their deep understanding of material development and battery applications. Foil manufacturers are extending their expertise in high-performance copper foil to lithium metal deposition and composite current collectors, with Yinglian Co. expected to play a key role in developing new deposition processes and structures [3] Technical Path - Rolling methods for lithium foil production are currently the most mature, while vapor deposition methods show superior performance and industrial feasibility. The rolling method produces lithium foil with a thickness of approximately 20-50μm, while vapor deposition can theoretically achieve thicknesses below 10μm, although it requires significant initial investment and is still in the experimental phase [4]
