Multiphysics Simulation for the Design of Lithium Ion Batteries

Multiphysics Simulation for the Design of Lithium Ion Batteries

By Ed Fontes (COMSOL), Henrik Ekström (COMSOL), and Andreas Nyman (Intertek) Introduction Lithium-ion batteries have become the most common rechargeable batteries for consumer electronics and automotive applications due to their high energy densities, decent power density, relatively high cell voltages, and low weight-to-volume ratios. The term lithium-ion battery refers to an entire family of battery chemistries. The common properties of these chemistries are that the negative and the positive electrode materials serve as hosts for lithium ions and that the battery contains a nonaqueous electrolyte. The increased demand and the pressure for improving battery performance have intensified the need for mathematical modeling. Modeling and simulations allow for the analysis of an almost unlimited number of design parameters and operating conditions at a relatively small cost. ...
