SABERS: Solid-State Lithium-Sulfur Battery Technology Portfolio
The SABERS innovators developed novel lithium-sulfur designs, including sulfur-selenium on graphene cathodes, and lightweight bipolar plate stacking and packaging designs. SABERS is unique in several aspects, in particular, it deploys graphene-based manufacturing processes for the cathode and bipolar plates, and it uses a solid-state electrolyte in place of the liquid electrolyte found in other lithium-sulfur battery designs. The team has achieved energy densities over 500 W-hr/kg, with ongoing development targeting further improvements. Coin cell and pouch prototype demonstrations have been successful and are ongoing.
Major component technologies in SABERS include the following:
• S/Se Cathode – Sulfur/Selenium on graphene scaffold (LEW-20228-1)
• Solid Electrolyte – Solid-state electrolyte composites (LEW-20445-1)
• Bipolar Stack – Graphene plates (LAR-20257-1)
Robust computational models have been developed to support the battery materials design and are available to licensees to evaluate and optimize different materials combinations and performance targets.
Further developments in catholyte formulations, anode interlayering, and packaging optimization are presented in SABERS 2.0 (LEW-TOPS-188). Individual technologies can be licensed from either suite, or entire portfolios can be licensed to support solid-state battery development programs.
