And second, if some of the vanadium in one tank flows through the membrane to the other side, there is no permanent cross-contamination of the electrolytes, only a shift in the oxidation states, which is easily remediated by rebalancing the electrolyte volumes and restoring the oxidation state via a minor charge step.
Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design. In the everyday batteries used in phones and electric vehicles, the materials that store the electric charge are solid coatings on the electrodes.
To measure the performance of the self-made vanadium electrolyte, a constant current charge–discharge test and cyclic stability test were carried out on the self-made and commercial vanadium electrolyte. The battery is divided into end plate, graphite plate, carbon felt, and Nafion115 membrane from the outside to the inside.
