A novel numerical model for the organic redox flow battery is built, and this model is verified by the experiments. The results show that the mass transfer and battery performances are influenced by the electrode thickness significantly. Taking the ohmic loss into consideration, the optimal electrode thickness is 1.5 mm.
The results show that the mass transfer and battery performances are influenced by the electrode thickness significantly. Taking the ohmic loss into consideration, the optimal electrode thickness is 1.5 mm. The rising of electrode channel depth significantly reduces the discharge voltage.
The influence of the shape of the electrodes on the flow batteries is mainly reflected in the internal polarization and pumping consumption of the battery. The reason for this is that the change of electrode shape can significantly affect the electrolyte distribution, flow rate, and mass transfer correlation.
Our numerical study suggest that the VRFB with specific electrode thickness and electrolyte flow rate shows optimum power-based efficiency. We concluded that the maximum power-based efficiency of 96.8% was achieved at the electrolyte flow rate of 10 ml/min and electrode thickness of 1 mm.
