Flow batteries are a new type of energy storage that hold great promise for the future, particularly in large-scale industrial applications . These batteries function by charging an electrolytic medium and then releasing stored energy, allowing them to convert electrical energy into chemical energy.
Currently, the most typical and commonly used performance evaluation method for flow batteries is charging–discharging test, mainly indicating four characteristics: (1) Coulombic efficiency (CE), the ratio of the average discharging capacity to the average charging capacity, (2) Voltage efficiency (VE), the ratio of the average discharging voltage to the average charging
