We derive PDE-based models for battery electrodes, which are subject to mechanical deformation as well as phase separation upon ion intercalation. We consider three main aspects:
(i) the electro-chemo-mechanical modeling of a non-phase separating single particle,
(ii) the modeling of an N-phase single particle,
(iii) the homogenization of porous electrodes with combined mechanical interactions and phase separation.

Accompanying numerical simulations will be carried out to investigate the behavior
of the derived models in comparison to real electrode materials.
