Fig. 1 is a simplified illustration of a battery system's thermal behavior. The total heat output in a battery is from many different processes, including the intercalation and deintercalation of the existing ions (i.e., entropic heating), the heat of phase transition, overpotentials, and the heat discharge due to mixing.
For instance, Jilte and Kumar investigated cooling performance of the battery module at a constant current discharge rate of about 6.94 C (25 A). The study reports that the battery module's two side walls were left completely open to allow cooling material to enter and exit, resulting in improved heat dissipation.
