AB - Metal-organic frameworks are beginning to be employed in the thermal  management system of lithium-ion batteries because of its high water  absorption and enthalpy of phase change. However, its cooling performance is  only preliminarily explored used in small cylindrical cells or a single  large cell. The effect on multiple large-capacity cells has not be verified  yet. In this study, a micro heat pipe arrays@MIL-101(Cr) hybrid battery  thermal management system is proposed, and its cooling performance of  different number of battery modules at different discharge rates is studied.  Experimental results show that MIL-101(Cr) is evenly distributed, and the  water vapor adsorption capacity reached 1.65 g/g. The maximum temperature of  the micro heat pipe arrays@MIL-101(Cr) group was 36.42°C in the experiment  of the four-cell battery pack at 1C discharge rate, which was 12.98°C lower  than that of the natural cooling group and 3.05°C lower than that of the  micro heat pipe arrays group. With the increase of the number of cells, the  maximum temperature of the battery pack rises from 43.12°C to 47.37°C, and  the temperature difference rises from 1.53°C to 5.57°C at 2C discharge rate.  As the discharge rate increases, the maximum temperature of the battery  consisting of four cells rises from 36.42°C to 47.37°C, and the maximum  temperature difference rises from 2.87°C to 5.57°C, which suggests that the  current micro heat pipe arrays@MOF based battery thermal management system  be combined with an active thermal management system to ensure temperature  control in high-rate and multi-battery modules.
