Lithium-Ion Battery Impedance - new

The impedance of a lithium-ion battery cell with a negative LTO and positive NCA electrode is modeled for harmonic perturbations between 10 mHz to 1000 Hz. The model incorporates an additional double-layer current at the conductive material in the positive electrode. The impedance of each electrode is also possible to investigate versus a reference electrode located in the middle of the ...

1D Lithium-Ion Battery Drive-Cycle Monitoring

This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. In the figure, an example of an electric vehicle with three critical components of a simplified battery management system is displayed. When the vehicle runs according to a specific drive cycle, the temperature and voltage of the battery ...

1D Isothermal Lithium-Air Battery - new

Rechargeable lithium-air batteries have recently attracted great interest mainly due to their high energy density. The theoretical value is about 11400 Wh/kg which is around 10 times greater than the lithium-ion batteries. In this tutorial, discharge of a lithium-air battery is simulated using the *Lithium-ion Battery* interface. The transport of oxygen (from external air) in the porous carbon ...
