Publication: New non-invasive method to monitor and reverse faradaic imbalance in redox flow batteries

State-of-health monitoring is key for the correct operation of redox flow batteries, which are affected by parasite reactions like Faradaic imbalance. This work proposes a new non-invasive monitoring method based on the minimum derivative of the cell voltage, used as the input that controls a rebalancing device to recover the capacity loss, extending the battery lifetime.
