08:50 AM EDT, 06/03/2025 (MT Newswires) -- Standard Lithium Ltd. ( SLI ) , a near-commercial lithium company, announced Tuesday the successful production of battery quality lithium sulfide as part of a collaboration with Telescope Innovations.

A statement noted Standard Lithium ( SLI ) has been working with its research and development partner, Telescope Innovations, to develop "new and novel" conversion technologies to make next generation battery materials. It said this new conversion process has now been successfully used to convert lithium hydroxide produced by Standard Lithium ( SLI ) at its southern Arkansas Demonstration Plant, into battery quality lithium sulfide. Samples of the lithium sulfide have been shipped to solid-state battery companies in Asia and North America for ongoing testing and validation purposes.

Standard Lithium's ( SLI ) President and COO, Dr. Andy Robinson said: "Whilst our principle area of focus, and capital allocation, is building the first DLE project in North America at our South West Arkansas Project Phase 1 with our joint venture partner Equinor, we understand that constant technological evolution is integral to staying at the forefront of this rapidly evolving industry. This recent work led by Telescope demonstrates that we are able to take lithium chemicals produced from the Smackover Formation in southern Arkansas, and then transform them into the feedstocks required by the next generation of batteries. Our partnership with Telescope Innovations continues to be a "win-win" for our shareholders and theirs. "
