A key advantage to redox flow batteries is the independence of energy capacity and power generation. The capacity of the battery is related to the amount of stored electrolyte in the battery system, concentration of active species, the voltage of each cell and the number of stacks present in the battery .
One disadvantage of vanadium redox-flow batteries is the low volumetric energy storage capacity, limited by the solubilities of the active species in the electrolyte. The cost of vanadium may be acceptable, because it is a relatively abundant material, which exists naturally in ~65 different minerals and fossil fuel deposits.
Vanadium redox flow batteries are currently not suitable for most mobile applications, but they are among the technologies which may enable, when mature, the mass adoption of intermittent renewable energy sources which still struggle with stability of supply and lack of flexibility issues.Copyright © 2014 John Wiley & Sons, Ltd.
Among all the redox flow batteries, the vanadium redox flow battery (VRFB) has the following advantages: technology maturation, wide range of applications, low maintenance cost, strong load balancing ability, and long cycle life.
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.
Fuel cell performance differs from redox flow batteries though. Further discussion indicates the dimensions of the bipolar plate, the number of channels and the permeability of the electrode all play a crucial role in the distribution of electrolyte, which could lead one path to be more effective than the other .
