In liquid cooling systems, a liquid is used as a refrigerant to remove heat generated by a battery. Compared with air, liquids have greater thermal conductivity, thinner boundary layers and greater heat capacities [129]. Depending on whether the liquid is in contact with the battery, the system provides either direct or indirect liquid cooling.
