Adding Mass Transport
Move on to extend the model to investigate the battery voltage over time at a certain load current. Start by adding a physics interface to handle the mass transport of zinc ions. The ions can be regarded as diluted in the orange interior making the Transport of Diluted Species interface suitable for modeling the mass transport.
