Redox flow batteries offer a readily scalable solution to grid-scale energy storage, but their application is generally limited to ambient temperatures above 0 °C. Now, a polyoxometalate-based chemistry has been developed to enable redox flow batteries to operate, and even thrive, under frigid conditions.
