Temperature field evolution of cylindrical battery: In-situ visualizing experiments and high fidelity internal morphology simulations

Modeling and measurement of the temperature distribution in cylindrical Li-ion cells are critical challenges that directly affect both the performance and safety. Most available electrochemical-thermal models for cylindrical cells are validated through the surface temperature. In this paper, high fidelity internal morphology two-dimensional electrochemical-thermal models based on geometric parameters extracted from computed tomography images are...
