Temperature Propagation during Cell Stacking Processes for Lithium-Ion Cells
Publié en 2015
A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal stressing. Results show a maximum local temperature of 180 °C at the jelly roll after laser welding for 4 s at 1500 °C. Further studies on various stress scenarios that represent cell stacking processes at elevated temperature will be performed.
