“…Macro length-scale models of VRFBs can be generally categorised into two groups: (1) lumped models, which mainly serve as control and monitoring tools, and (2) distributed models, which capture the spatial variations of eld variables within the cell and can be employed for cell design and optimisation. 49,198 Lumped models on the system level address the prediction of stack voltage, state-of-charge (SOC), state-of-power (SOP), ow rate and system efficiency in different SOCs by using global mass and energy balances. 49,52,199,200 These models are suitable to simulate transient characteristics such as mechanical (pumping) and electrochemical performance oen based on a unit cell.…”

“…Examples of such charts are provided by Viswanathan et al[169] in their costperformance model and by Xu and Zhao[170] in their timely review of fundamental models for flow batteries. For example,Figure 15indicates a flow chart to summarise the approach taken by Bayanov[171].Traditionally, there have been few examples of practical models validated by operational experience and experimental validation but there is evidence of much recent effort, especially for the all vanadium RFB. Examples include cell voltage vs. time during a charge-discharge cycle and soluble lead concentration distributions…”

Despite many studies and several extensive reviews of redox flow batteries (RFBs) over the last three decades, information on engineering aspects is scarce, which hinders progress with scale-up and implementation of this energy storage technology. This review summarises cell design requirements then critically considers design, construction and cell features together with their benefits and problems, leading to good practice through improved cell performance, knowledge and experience. Techniques for the characterisation of the reaction environment are illustrated by measurements of mass transport to (and from) electrode surfaces as a function of flow conditions, as well as pressure drop and electrolyte flow dispersion. The effect of design features on performance is illustrated by the effect of process conditions on the components of cell potential. Adequate attention to engineering aspects is seen to be critical to the effective performance of RFBs, particularly during scale-up and long-term operation. Techniques for the characterisation of reaction environment are summarised and a list of essential design and construction factors is provided. Finally, critical areas needing research and development are highlighted.
