Initial Concentration Calculations

class ionworkspipeline.calculations.InitialSOC(soc)

Calculate the initial concentration in the negative and positive electrodes from the initial SOC and stoichiometry windows in each electrode.

Parameters

socfloat

The state of charge to calculate the initial concentration at.

Extends: ionworkspipeline.calculations.calculation.Calculation

class ionworkspipeline.calculations.InitialSOCHalfCell(electrode, soc)

Calculate the initial concentration in the given electrode from the initial SOC and stoichiometry window.

Parameters

electrodestr

The electrode to calculate the initial concentration for. Must be either “negative” or “positive”.

socfloat, int, or str

The state of charge to calculate the initial concentration at. If a string is provided, it should match the name of a “Electrode stoichiometry at X SOC” parameter in the parameter values dictionary, e.g. “0%”, “100%”, “minimum”, “maximum”.

class ionworkspipeline.calculations.InitialVoltageFromConcentration(electrode)

Calculate the initial voltage in the given electrode from the initial concentration (i.e. find the voltage that gives the correct concentration).

Extends: ionworkspipeline.calculations.calculation.Calculation

class ionworkspipeline.calculations.InitialStoichiometryFromVoltageHalfCell(electrode, options=None)

Calculate the initial stoichiometry in the given electrode from the initial voltage (i.e. find the stoichiometry that gives the correct voltage).

Parameters

electrodestr

The electrode to calculate the initial concentration for, either “positive” or “negative”.

optionsdict, optional

A dictionary of options to be passed to the calculation. The following options are available:

• simulation_kwargs: dict

  Keyword arguments to pass to the simulation (iwp.Simulation). Default is {“solver”: pybamm.AlgebraicSolver()}.

class ionworkspipeline.calculations.InitialStoichiometryFromVoltageMSMRHalfCell(electrode)

Calculate the initial stoichiometry in the given electrode from the initial voltage (i.e. find the stoichiometry that gives the correct voltage) using the MSMR framework.

Parameters

electrodestr

The electrode to calculate the initial concentration for, either “positive” or “negative”.
