New recycling processes for secondary batteries are needed to achieve sustainable use of natural
resources. Indeed, many components in lithium ion batteries, such as cobalt and graphite, are in the
European Union’s “Critical Raw Materials” list. Electrodialytic treatment of disposed lithium-ion
batteries is a pioneer proposal for the selective recovery of some of these relevant elements.
In this work, a model for the electrochemical technology of disposed batteries implemented
using COMSOL Multiphysics is presented. The main aim of this model is the optimization of the
extraction of valuable components from spent batteries and the prediction of experimental results, which
entails a better understanding of the different process involved. The model is based on the Nernst-Planck-
Poisson system of equations coupled with the local chemical equilibrium conditions. The model uses
multi-scale discretization of the different components; including the assumed well-stirred compartments,
the ion-exchange membranes and the diffuse double-layer at the surface of the membranes. Different cell
configuration has been tested, and results were compared to experimental data for model validation.
