Indeed, many components in lithium ion batteries, such as cobalt and graphite, are in theEuropean Union’s “Critical Raw Materials” list. Electrodialytic treatment of disposed lithium-ionbatteries 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 implementedusing COMSOL Multiphysics is presented. The main aim of this model is the optimization of theextraction of valuable components from spent batteries and the prediction of experimental results, whichentails 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 usesmulti-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 cellconfiguration has been tested, and results were compared to experimental data for model validation.
