STANDARD LITHIUM LTD.

Standard Lithium Ltd. announced the successful downstream battery testing of lithium carbonate produced from its South West Arkansas (SWA) Project pilot plant. Nano One Materials Corp. successfully used the battery-quality lithium carbonate to manufacture lithium iron phosphate (LFP) cathode active material (CAM) and battery coin cells. This testing validates the SWA Project's process flowsheet and the suitability of its lithium carbonate for downstream applications, supporting the development of a domestic energy storage supply chain.
