Inverse Butler-Volmer

class pybamm.kinetics.InverseButlerVolmer(param, domain, reaction, options=None)

A submodel that implements the inverted form of the Butler-Volmer relation to solve for the reaction overpotential.

Parameters:
  • param – Model parameters

  • domain (iter of str, optional) – The domain(s) in which to compute the interfacial current.

  • reaction (str) – The name of the reaction being implemented

  • options (dict) – A dictionary of options to be passed to the model. In this case “SEI film resistance” is the important option. See pybamm.BaseBatteryModel

  • **Extends (** pybamm.interface.BaseInterface) –

get_coupled_variables(variables)

A public method that creates and returns the variables in a submodel which require variables in other submodels to be set first. For example, the exchange current density requires the concentration in the electrolyte to be created before it can be created. If a variable can be created independent of other submodels then it should be created in ‘get_fundamental_variables’ instead of this method.

Parameters:

variables (dict) – The variables in the whole model.

Returns:

The variables created in this submodel which depend on variables in other submodels.

Return type:

dict
