ABQ_EChemPET_Electrode_Particle_ButlerVolmer

This parameter table type is used in modeling the electrochemical process in a battery to specify the coefficients to use to compute the current density using the Butler-Volmer equation.

This page discusses:

You must include a parameter table of type "ABQ_EChemPET_Electrode_Particle_ButlerVolmer" in the material definition to specify the coefficients to use to compute the current density using the Butler-Volmer equation.

Parameters

k c
Cathodic rate constant.
k a
Anodic rate constant.
α c
Cathodic transfer coefficient.
α a
Anodic transfer coefficient.
C e ref
Reference value of the lithium concentration in the electrolyte.
R SEI
Resistance value of the solid electrolyte interphase (SEI) layer.
Stress coef
Partial molar volume coefficient for the hydrostatic stress at the particle surface.
a s
Set this value to 0.0 to use the value computed by Abaqus. If you specify a nonzero value, the specified value is used for the wetted surface area of the particle.
