Standard Lithium Ltd. Achieves Breakthrough in Battery-Quality Lithium Sulfide Production

Standard Lithium Ltd. (NYSE American: SLI) has marked a significant milestone in the lithium industry with the successful production of battery-quality lithium sulfide (Li₂S) using an innovative, low-temperature conversion process. This development, achieved in partnership with Telescope Innovations, utilizes lithium hydroxide from Standard Lithium's southern Arkansas Demonstration Plant. The method stands out for its high impurity tolerance, feedstock flexibility, and improved safety, positioning it as a promising solution for the growing solid-state battery market. Samples of the lithium sulfide have already been sent to battery manufacturers in Asia and North America for validation, signaling a potential shift in how battery materials are produced and utilized.

Dr. Andy Robinson, President and COO of Standard Lithium, emphasized the strategic importance of this technological breakthrough. While the company continues to prioritize its South West Arkansas Project in collaboration with Equinor, advancements such as this are vital for maintaining a competitive edge in the fast-evolving lithium sector. Standard Lithium's dedication to sustainable, commercial-scale lithium production is further highlighted by this achievement, showcasing the company's commitment to innovation and environmental responsibility.

The company's projects in the Smackover Formation, spanning Arkansas and Texas, are central to its strategy of exploiting high-grade lithium-brine properties. Collaborations with Equinor ASA on the South West Arkansas Project and LANXESS Corp. on the phase 1A project in southern Arkansas demonstrate Standard Lithium's approach to sustainable lithium production, leveraging existing infrastructure and efficient permitting processes. Additionally, the company's exploration of mineral leases in the Mojave Desert in San Bernardino County, California, reflects its ambition to expand its footprint in the lithium resource sector.

This breakthrough not only solidifies Standard Lithium's position as a leader in the lithium market but also contributes to the global transition towards cleaner energy solutions. The production of battery-grade lithium sulfide through a low-temperature process is a critical advancement in addressing the increasing demand for high-performance battery materials. These materials are essential for the next generation of electric vehicles and renewable energy storage systems, underscoring the broader implications of Standard Lithium's achievement for the industry and the environment.
