KBR and ISU Scale-up Lithium Sulfide Production for Batteries

KBR and ISU Scale-up Lithium Sulfide Production for Advanced Batteries.

KBR and ISU Specialty Chemical Co. Ltd. have advanced their PureLi2SSM lithium sulfide technology to commercial scale, following the successful operation of the Onsan pilot plant in Ulsan, Republic of Korea.

Under the joint development agreement signed in 2023, the companies established a pilot plant that has successfully produced on-spec lithium sulfide, securing market acceptance. Insights from this phase, combined with KBR’s expertise in process technology scale-up, will be critical in designing the commercial facility to bring this technology to the global market.

KBR’s PureLi2S technology is designed to produce battery-grade lithium sulfide for All-Solid-State Batteries (ASSBs). These batteries offer higher energy density, enhanced safety, and superior efficiency over conventional liquid electrolytes.

The successful commercialization of this process is expected to advance the battery industry toward safer and more efficient energy storage solutions.
