Model Introduction:

This model is mainly about the simulation of bipolar plate flow channels in all vanadium flow batteries. The negative electrode of the battery consists of divalent and trivalent vanadium ions, while the positive electrode consists of tetravalent and pentavalent vanadium ions. The battery is charged and discharged through the conversion of ion valence states.

Introduction to Physical Fields

The model uses two physical fields, namely the cubic current distribution and the Blinkmann equation, which are a combination of electric field and flow field.
