mtnlion.models.sei module

Isothermal model extended with SEI layer growth

class mtnlion.models.sei.SEI(Ns)[source]

Bases: mtnlion.models.isothermal.Isothermal

The SEI model is an extension to the isothermal model that attempts to quantify solid-electrolyte interphase formation and growth on the negative-electrode solid particles during chargning.

class LocalMolecularFlux[source]

Bases: mtnlion.formula.Formula

The total flux of the system including intercalation flux and side reaction flux.

form(arguments, domain)[source]

This method must be overloaded to define the form of the Formula.

Parameters

  • arguments – All arguments defined by overriding one or more of Formula.Variables, Formula.Formulas, Formula.Parameters, Formula.Lambdas, and Formula.TimeDiscretization

  • domain – The current domain in which the function is being evaluated

Returns

FFL form

class Overpotential[source]

Bases: mtnlion.formula.Formula

Voltage difference between a reduction potential and the potential of the redox event.

form(arguments, domain)[source]
