Because the C-rate is the rate at which the thermal battery is discharged, the thermal power density of the storage material is P PCM [kW m −3] = S PCM C rate. A higher C-rate means that the battery is being discharged at a higher power (i.e., greater rate of heat transfer), which reduces the thermal resistance at cutoff.
