CENTURY LITHIUM REPORTS LITHIUM METAL FROM ANGEL ISLAND DEMONSTRATED IN BATTERY CELLS UNDER U.S. ARMY SBIR PROGRAM

About this update from Century Lithium Corp

VANCOUVER, BC, July 15, 2026 /CNW/ - Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt: C1Z) ("Century Lithium" or "the Company") is pleased to announce that lithium carbonate produced from its 100% owned Angel Island Lithium Project in Nevada, USA ("Angel Island") was successfully converted into lithium metal using Alpha-En Corporation's ("Alpha-En") proprietary extraction and electrodeposition process and incorporated into cylindrical cells manufactured by EaglePicher Technologies ("EaglePicher"). This work was supported by funding from the US Army Small Business Innovation Research ("Army SBIR") program, which aims to accelerate the development of innovative technologies critical to national defense. "Alpha-En has done outstanding work converting lithium carbonate from Angel Island into high-purity lithium metal, which was then incorporated by EaglePicher in cells tested under the U.S. Army SBIR program," said Bill Willoughby, President and CEO of Century Lithium. "The results from this first phase program are important for Century Lithium and further highlight Angel Island as a quality domestic source of lithium." The lithium metal anodes produced from Angel Island lithium carbonate by Alpha-En met EaglePicher's performance specifications and were integrated into EaglePicher's cylindrical cells for testing. Initial discharge results demonstrated higher operating voltages and improved power performance compared to the control cells, key attributes for demanding defense applications which require lightweight, high-energy, and high-power battery systems. "This Army SBIR-supported effort demonstrates that high-performance lithium metal anodes can be manufactured directly from US-sourced lithium resources," said Landon Oakes, Chief Technology Officer of Alpha-En. "By integrating domestic raw materials with our membrane extraction and electrodeposition platform, we are establishing a secure, vertically integrated pathway for next-generation battery anodes that reduces reliance on foreign supply chains." This successful demonstration represents a significant step toward strengthening the domestic defense battery supply chain. By connecting US-based lithium resources, advanced lithium metal manufacturing, and domestic cell fabrication, the collaboration supports the US Army's objective of securing critical mineral independence while advancing high-performance battery technologies for future defense systems.
