On the negative side, flow batteries are rather complicated in comparison with standard batteries as they may require pumps, sensors, control units and secondary containment vessels. The energy densities vary considerably but are, in general, rather low compared to portable batteries, such as the Li-ion.
Designing the flow field in the fuel cell helps to improve the efficiency and performance of the battery. Therefore, VRFB researchers introduce the flow field into the battery research to explore the influence mechanism of the flow field on VRFB [, ].
In summary, the comparative study on the battery performance of the flow field of different flow channels can provide inspiration for the design and optimization of the battery flow field. The VRFB is a promising energy storage system that provides efficient energy storage solutions for intermittent renewable energy such as wind energy and PV.
Flow batteries, while offering advantages in terms of decoupled power and energy capacity, suffer from lower energy density due to limitations in the solubility of active materials and electrode capacity. The broad voltage windows of non-aqueous electrolytes in flow batteries can also impact their energy density.
The excellent flow field structure has a greater impact on the internal pressure drop and concentration polarization phenomenon of the battery . The pressure drop is the energy loss of the VRFB system, which will directly affect the EE of the battery. The greater the, pressure drop, the greater the energy loss .
Flow batteries are seen as one promising technology to face this challenge. As different innovations in this field of technology are still under development, reproducible, comparable and verifiable life cycle assessment studies are crucial to providing clear evidence on the sustainability of different flow battery systems.
