- Lithium carbonate produced from the South West Arkansas Project pilot plant successfully used by Nano One® to manufacture lithium iron phosphate (“LFP”) cathode active material (“CAM”) and battery cells in North America
- Testing provides further validation of SWA Project’s process flowsheet and the suitability of its battery-quality lithium carbonate in downstream applications
- Advances Standard Lithium’s commitment to technological innovation and support for development of a domestic, fully-integrated energy storage supply chain
VANCOUVER, British Columbia, Aug. 13, 2026 (GLOBE NEWSWIRE) -- Standard Lithium Ltd. (“Standard Lithium” or the “Company”) (TSXV: SLI) (NYSE.A: SLI), a leading near-commercial lithium company, is pleased to announce the successful downstream battery testing of lithium carbonate produced from its South West Arkansas project (the “SWA Project”).
Standard Lithium provided approximately one kilogram of battery-quality lithium carbonate produced using the SWA Project’s brine and process flowsheet (see press release dated 11 March 2025) to Nano One® Materials Corp. (“Nano One”). Nano One successfully used that material in its patented One-Pot™ process to produce LFP CAM, followed by battery coin cells for testing.
The resulting material demonstrated desired chemical and physical properties, achieved the intended particle morphology and delivered approximately 155 mAh/g on first discharge in initial electrochemical testing.
Dr. Andy Robinson, President and Chief Operating Officer of Standard Lithium, commented: “We have spent years testing and developing an integrated process flowsheet designed to produce a high-quality lithium product to meet the stringent needs of the battery industry. Our recent work alongside Nano One provides some exciting additional real-world validation of the work we have done.”
“We also understand that building a secure domestic battery and energy storage supply chain requires more than just lithium production in the United States. There remains a significant gap between domestic demand needs and the planned production of critical battery raw materials and components, like CAM, to support it. Standard Lithium is well positioned to be a champion in the development of a complete supply chain, including by working with innovative companies such as Nano One that can help provide a solution for the missing midstream in the U.S.”
The test work completed is part of Standard Lithium’s broader efforts to support technology development opportunities and to engage with novel companies across the value chain. These collaborations enhance the Company’s understanding of evolving customer requirements and support the development of a more resilient and competitive domestic battery industry.
