Battery storage systems become increasingly more important to fulfil large demands in peaks of energy consumption due to the increasing supply of intermittent renewable energy. The vanadium redox flow battery systems are attracting attention because of scalability and robustness of these systems make them highly promising.
In numerous energy storage technology, vanadium redox flow batteries (VRFBs) are widely concerned by all around the world with their advantages of long service life, capacity and power independent design [9, 10].
Various flow battery systems have been investigated based on different chemistries. Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems.
Li-Ion Batteries (LIBs) and Redox Flow Batteries (RFBs) are popular battery system in electrical energy storage technology. Currently, LIBs have dominated the energy storage market being power sources for portable electronic devices, electric vehicles and even for small capacity grid systems (8.8 GWh) .
Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems. The commercialized flow battery system Zn/Br falls under the liquid/gas-metal electrode pair category whereas All-Vanadium Redox Flow Battery (VRFB) contains liquid-liquid electrodes.
The graphite BPs in the corrosive vanadium electrolyte is easily eroded due to CO 2 gas evolution on the positive side of the VRFB electrode [92, 93]. The severe heterogeneous surface corrosion results in electrolyte leakage across the BP that significantly deteriorates the battery performance, which ultimately leads to battery failure.
