Analytical modeling and simulation of porous electrodes: Li-ion distribution and diffusion-induced stress
Published in Acta Mechanica Sinica
A new model of porous electrodes based on the Gibbs free energy is developed, in which lithium-ion (Li-ion) diffusion, diffusion-induced stress (DIS), Butler–Volmer (BV) reaction kinetics, and size polydispersity of electrode particles are considered. The influence of BV reaction kinetics and concentration-dependent exchange current density (ECD) o...
