Table S1 summarize the changes of charge–discharge capacity of the battery after 25 °C, 60 °C and 80 °C. The charge capacity also decreases after high-temperature storage. The decay of discharge capacity can be attributed to the acceleration of self-discharge under high temperature (R-Smith, 2023).
PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.

Local overheating of the battery (X 6) and short-circuit heat release outside battery (M 21) are the sources of high temperature. The overlap between positive and negative electrodes (X 7 ) and water inflow into the battery pack (M 22 ) may cause a short circuit and heat release outside the battery (M 21 ) [ 37 ].
