Perspectives of electrolyte future research are proposed. The vanadium redox flow battery (VRFB), regarded as one of the most promising large-scale energy storage systems, exhibits substantial potential in the domains of renewable energy storage, energy integration, and power peaking.
Vanadium redox flow battery (VRFB) has attracted much attention because it can effectively solve the intermittent problem of renewable energy power generation. However, the low energy density of VRFBs leads to high cost, which will severely restrict the development in the field of energy storage.
Traditionally, much of the global vanadium supply has been used to strengthen metal alloys such as steel. Because this vanadium application is still the leading driver for its production, it’s possible that flow battery suppliers will also have to compete with metal alloy production to secure vanadium supply.
Vanadium ion concentration, supporting electrolytes concentration, environmental temperature, and even the difference between positive and negative solution can all impact the viscosity, thus influencing the battery performance.
From these three points, changing the effective diffusion coefficient is the effective method such as redesigning the solvent structure of vanadium. While extensive modeling and simulation have explored the mechanisms of this phenomenon, experimental validation remains crucial.
The flow field is a key factor in determining the performance of VRFB, and a flow field with excellent performance can effectively improve the electrolyte flow distribution. A reasonable design of the VRFB flow field structure is an effective way to improve the efficiency and performance of the battery.
