Telescope Innovations Corp. announced it has filed a provisional patent application (65/584,062) on the production of lithium sulfide, a key precursor for next-generation solid-state batteries. As an outcome of work with Standard Lithium Ltd., Telescope has invented a low-temperature method of generating lithium sulfide from brine-sourced lithium chemicals.

This method could reduce the current high costs of lithium sulfide production, and so facilitate the widespread deployment of solid-state batteries. This accelerated discovery has fueled the growth of Telescope's IP portfolio, which already includes a granted Canadian patent on the production of pharmaceutically-relevant indole compounds.
