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 sulfurized–polyacrylonitrile (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.
SPAN–transition 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 methods lack precision, scalability, and safety.

Commercial gap: Battery developers and manufacturers lack access to a reliable process to enable large scale SPAN production needed to advance lithium-sulfur and sodium-sulfur chemistries.

Solution

INL’s approach provides both a production pathway and a material enhancement strategy:

Reactor-based controlled synthesis

Operates under high pressures (up to 3000 PSI) and high temperatures (up to 450°C) with the ability to eliminated headspace for safety and yield.
Captures noxious gases and allows gas reagent introduction.
Integrates electronic controls, real-time spectroscopy for product feedback, and reproducibility.
