Cyclable Lithium Calculations

class ionworkspipeline.calculations.CyclableLithium(options=None)

Calculation of amount of cyclable lithium capacity, either based on previously calculated electrode capacities and initial stoichiometries (“electrode capacities” option), or based on the initial positive electrode capacity and some formation loss (“formation loss” option). The latter option assumes that before formation the amount of cyclable lithium available is equal to the amount of lithium in the positive electrode (positive electrode starts our fully lithiated, negative electrode startts out fully delithiated), and that a fixed fraction, f, of that lithium is lost during the formation process. Then, the cyclable lithium capacity is given by

\[Q_Li = f * Q_p\]

where f is the parameter “Formation lithium loss” and Q_p is the parameter “Positive electrode capacity [A.h]”.

Parameters

optionsdict, optional

Options for the calculation. The available options are:

• “method”str

  The method to use to calculate the cyclable lithium capacity. Either “electrode capacities” or “formation loss”. Default is “electrode capacities”.
