Abstract

The broader/commercial impact of this Small Business Innovation Research Phase I (Fast-Track)project will be the development of a low-cost diagnostics platform that improves the reliability, safety, and lifetime of flow batteries for long-duration energy storage. This project will address gaps by developing sensors that monitor electrolyte composition in real time so operators can detect degradation before major…
