Controlled SPAN Electrode Synthesis for and High-Performance Energy Storage Scalable production and enhanced stability through advanced reactor design and transition metal sulfide integration Technology Summary Researchers at Idaho National Laboratory (INL) have developed an integrated approach to producing sulfurizedpolyacrylonitrile (SPAN) electrode materials at scale with improved electrochemical performance. This dual innovation combines: Controlled, scalable SPAN synthesis enabled by a custom high-pressure chemical reactor with real-time monitoring and additive reagent control. SPANtransition metal sulfide composites designed to enhance conductivity, sulfur utilization, mitigate polysulfide formation, prolong cycle life, and increase nominal discharge voltage performance in lithium-sulfur and sodium-sulfur batteries. The combined platform addresses longstanding barriers in SPAN production and performance, opening viable pathways for next-generation rechargeable batteries in grid storage, electric mobility, and defense applications. Problem Addressed Manufacturing barriers: Consistent, high quality SPAN cathode materials are difficult to produce in large batch sizes. Existing m...
