About Featured Expert: PolyJoule
PolyJoule is a Massachusetts-based energy storage technology company focused on the development of conductive polymer battery systems for stationary energy storage applications. Spun out from the Massachusetts Institute of Technology (MIT), the company develops non-metallic battery technologies designed to support long-duration energy storage, renewable energy integration, grid resilience, and distributed energy infrastructure.
The company’s conductive polymer battery chemistry is designed to provide an alternative to conventional lithium-ion systems by 
emphasizing operational safety, long cycle life, simplified thermal management, and domestic supply chain sourcing. PolyJoule’s battery platforms are intended for commercial, industrial, and utility-scale applications where reliability, thermal stability, and infrastructure simplicity are important operational considerations.
Unlike traditional battery chemistries that rely on metallic charge-storing materials, PolyJoule’s conductive polymer systems store charge along an organic polymer backbone. According to the company, this approach can help reduce risks associated with thermal runaway while supporting extended cycle life and eliminating dendrite formation associated with some battery technologies.
PolyJoule recently introduced its third-generation conductive polymer battery chemistry featuring a conductive polymer cathode and liquid salt electrolyte. The company states that the platform is designed to self-extinguish under extreme thermal conditions while operating without active thermal management systems in many stationary energy storage environments.
The company’s battery systems are designed and manufactured in the United States using domestic supply chains that avoid reliance on rare-earth materials and many internationally constrained raw material sources commonly associated with battery manufacturing.
PolyJoule’s technology platform is intended to support applications involving renewable energy storage, backup power systems, distributed energy infrastructure, microgrids, grid modernization, and long-duration stationary storage deployments. To learn more, please click here.
