Abstract
AbstractIn this paper, a linear electro‐chemo‐mechanical model for a structural Lithium ion battery electrode material is presented. The considered material is composed of particles (storing Lithium) embedded in a porous polymer matrix. The pores are filled with a liquid electrolyte. In this three phase material different processes are taken into account: ion diffusion and migration inside the electrolyte, Lithium diffusion inside the particles, electric current inside the binder matrix and particles as well as deformation in these two phases. After presenting the mathematical model, we perform a numerical study of a simple system to investigate the model behavior.
