Thermal Modeling of Lithium-ion Batteries with LiFePO4 Electrodes

We develop a three-dimensional, multi-scale, multi physics lithium-ion battery model wherein a mesoscale spherical particle model is considered an electrode particle domain and a single cell domain. The model is first compared with the experimental voltage data measured at various discharge and charge current densities. The model predictions present key electrochemical and transport phenomena in lithium-ion batteries. Moreover, contours of solid electrode/electrolyte, temperature, and current density are presented under several different time to highlight insight into discharge and charge behaviors of lithium-ion batteries.
