Flow channel optimisation of iodine zinc flow battery modelling.

By analysing the flow field of the bipolar plate, considering the inlet and outlet direction, increasing the inclined baffle and the number of channels, an improved multi-channel serpentine flow channel on the opposite side of double baffles is obtained based on the traditional serpentine flow channel. And the hydrodynamic model, electrochemical model and equivalent circuit model are coupled into a hybrid model to obtain the relationship between pump loss current changes during charging and discharging. The experimental results show that the reaction time of the change curve is 52 s earlier and the charging cut-off voltage is 0.3 V higher in the charging and discharging state. [ABSTRACT FROM AUTHOR]
