The thermal-electrochemical model was validated for discharge rate capability tests at various temperatures, the temperature during these experiments was monitored to validate the heat generation component of the model. The heat generation was measured using an external thermocouple on the cylindrical cell. Before the experiment there is a two hour rest period to record the initial state. Then the cell was charged at 0.3C with a C/100 current cutoff for the CV step, and discharged at C/10, C/2, 1C, and 2C using a Maccor battery tester. The voltage window used was 2.5 V -4.2 V. Between each charge and discharge there was a two hour rest period. The testing protocol was carried out at 0 °C, 10 °C, and 25 °C with the chamber temperature being measured throughout the experiment.
