The University of South Carolina is offering licensing opportunities for Lithium Sulfur Battery Electrode Process
Sulfur is a promising candidate for next-generation cathodes in Li battery systems. However, modern Li-S cathodes cannot be extensively cycled.
The present innovation provides a simple and low-cost processing method to create electrodes that allow for significantly improved cycling and lifetime. The cyclability of Li-S batteries is improved by developing a new method to make electrodes. The concept involves controlling how much the adhesive binder dissolves into the processing solvent. The result is longer battery life, allowing these cells to penetrate new applications.
If Li-S supplants Li-ion, it could be a multi-billion-dollar industry, with the market share for electrode manufacturing being 5-10% of that market.
Advantages and Benefits:
The current innovation provides a simple and low-cost processing method to make Sulfur cathodes with a more durable cycle life through the utilization of conventional sulfur cathode materials including elemental sulfur, carbon black, and a polymer binder. Potential licensees will be able to use this method at scale and provide a low-cost Sulfur cathode with superior performance to the battery market.
