During the redox reaction, the anolyte loses an electron and gets oxidised. This electron flows through the external circuit and reaches catholyte where the catholyte will accept the electron and gets reduced. The charging and the discharging processes are illustrated in Fig. 3 for the vanadium flow battery.Web
