An overview of the design and optimized operation of vanadium redox flow batteries for durations in the range of 4-24 hours
Abstract
An extensive review of modeling approaches used to simulate vanadium redox flow battery (VRFB) performance is done. Materials development is reviewed with opportunities for additional development are identified. The various crossover mechanisms for the vanadium species are reviewed, and their effect on state of charge and state of health assessed. Stack design focusing on flow fields and electrode design tailored for various flow fields are reviewed. Operational strategy taking into account these parameters is reviewed for various operating envelops chosen depending on end user preference. This work provides a framework for the design and operation of a VRFB for various grid services.Published: May 13, 2023
