A simple model for the vanadium redox battery

Development of the all-vanadium redox flow battery for energy storage: a review of technological, financial and policy aspects

“…A similar model was recently developed by Shah and co-workers for the all-vanadium system [111]. Although not able to capture the same level of detail at the unit cell scale as the models in [103][104][105][106][107][108], the equivalentcircuit approach is the ideal basis for control applications and stack/system-level modelling [112,113].…”

“…The multi-dimensional, dynamic equations were solved for a range of operating conditions (including temperature, mean electrolyte flow rate, initial reactant concentration) and validated against experimental data. The steady-state all-vanadium case was simulated by You et al [108]. These studies provide detailed predictions of the reactant, current density and potential distributions within the electrodes, under the various operating conditions.…”

A three-dimensional model for negative half cell of the vanadium redox flow battery

“…In this paper, based on the model presented by Shah et al [12] and You et al [16], a stationary, isothermal, three-dimensional model for negative half cell of the vanadium redox flow battery is presented. The model is described by the comprehensive conservation laws like charge, mass and momentum, together with a kinetic model for reaction involving vanadium species.…”

“…The model studied the effect of variation in concentration, electrode porosity and electrolyte flow rate on the performance of cell, even taken into account non-isothermal effect [13] which was done by adding an energy equation and gas-evolving side reactions including oxygen [14] and hydrogen [15] evolution. Based on the dynamic model developed by Shah, You et al [16] developed a simplified stationary model through introducing SOC (state of charge). The effects of applied current density, electrode thickness ratio and local mass transfer coefficient on the performance of all-vanadium redox flow battery were studied.…”

Cell architecture upswing based on catalyst coated membrane (CCM) for vanadium flow battery

“…The improvement can be attributed to the usage of CCM, on which the electro-catalyst layer has accelerated the progress of electrode reactions. You et al reported a twodimensional stationary mode to describe a single vanadium flow cell based on the universal conservation laws and coupled with electrochemical reactions [26]. According to the result, the electrode reaction over-potential closed to the membrane side is relatively large.…”
