Battery Electrode with a Particle Size Distribution

Application ID: 116471

Battery electrodes featuring large heterogeneities in terms of particle sizes may sometimes not be adequately described by homogenized models using one single particle size only.

As an alternative to adding multiple instances of the Additional Porous Electrode material node, this tutorial demonstrates how to instead deploy a user-defined Extra Dimension to define the solid phase diffusion of intercalated lithium for a range of particle sizes.

A histogram is used as input in the model in order to define the distribution of particle sizes in the electrode.

This model example illustrates applications of this type that would nominally be built using the following products:
