Lithium-Ion Capacitor - Optimization of Thermal Management from Cell to Module Level

This paper represents the thermal behavior of a lithium-ion capacitor. In this study, an extended parameter analysis has been realized for observing the thermal behavior when applying dedicated load profiles. Based on the performed analysis, an electro-thermal model and a 3D thermal model have been developed for future optimization of a thermal strategy. The model has been implemented using COMSOL Multiphysics and parameters were obtained from experiments on a 2300-F lithium-ion capacitor cell from JM energy. The accuracy of this model is tested under different operating conditions and simulations are in agreement with experimental results. The developed models are in good agreement with the experimental results, which indicates that the models can be used for the design and optimization of the thermal management.
