Thermal-Electrochemical-Stress Simulation of Li-ion Batteries
This course introduces cell-level multiscale, multiphysics analysis of the electrochemical performance of Li-ion batteries based on porous electrode theory. The thermal effects from various losses (associated with the ionic diffusion, electrical conduction, entropy change, and intercalation) and the mechanical effects due to lithiation-induced swelling are considered in a fully coupled manner.
