제목 Mathematical modelling and simulation of the effect of adhesive strength on the electrochemical performance of silicon based lithium ion batteries
초록 A coupled chemo-mechanical model which considers the contact resistance as well as the influence of the attractive forces inside the contact area between the electrode and current collector is developed to demonstrate the effect of the adhesive strength of binding materials on the electrochemical performance of silicon based lithium ion batteries. The developed model is incorporated into the Newman’s Porous Composite Electrode (PCE) framework and implemented in the COMSOL Multiphysics battery module to simulate the rate performance of Li/Si half-cell. The proposed model is used to investigate the specific capacity as a function of silicon electrode thickness, lithium ion concentration in the electrolyte, and silicon particle size.
