In article number 1900494 by Zhiqun Daniel Deng, Wei Wang, and co‐workers, an ultrasonic probing approach that can measure the acoustic properties of a vanadium redox flow battery electrolyte is designed to monitor the state‐of‐charge (SOC) of flow batteries online noninvasively. The SOC estimated from the acoustic attenuation coefficient is found to be robust to temperature variation.
