A battery thermal management system (BTMS) plays a significant role in the thermal safety of a power lithium-ion battery. Research on phase change materials (PCMs) for a BTMS has drawn wide attention and has become the forefront of this scientific field. Several evident limitations exist in pure PCMs, such as poor thermal conductivity and low structural stability, while porous materials could reinforce PCMs for their superior thermal performance and robustness. Most related existing reviews focused on the thermal performances of a lithium-ion BTMS by different cooling methods. However, the thermal properties of porous materials and those based composite phase change materials (CPCMs) have not been summarized, which have much influence on the thermal management effect of battery modules. Thus, research on porous-material-based CPCMs used for a lithium-ion BTMS were reviewed in this paper. The kinds of PCMs and porous materials commonly used in a lithium-ion BTMS were introduced, and the thermophysical properties and robustness of porous-material-based CPCMs were systematically analyzed. Furthermore, the thermal management effects of a porous-materialbased CPCM on a lithium-ion battery were summarized. We discussed the enhancement effects on PCMs and the advantages and limitations of various porous materials commonly used in a lithium-ion BTMS. Finally, on the basis of the current research, this paper concluded the requirement of porous material for a CPCM in a lithium-ion BTMS and the expected future research directions of porous material, including looking for a potential porous carrier, intensifying heat transfer, and enhancing anti-vibration performance.

Due to strict regulations and the requirement to reduce greenhouse gas emissions, electric vehicles (BEVs) are a promising mode of transportation. The lithium battery is the most important power source for an electric vehicle, but its performance and life are greatly restricted by temperature. To ensure the safety of automobile operation and alleviate mileage anxiety, it is urgent to understand the current situation and predict the development and challenge of battery thermal management system. This work reviews the existing thermal management research in five areas, including cooling and heating methods, modeling optimization, control methods, and thermal management system integration for lithium batteries. Battery thermal management types include air-based, liquid-based, PCM-based, heatpipe-based, and direct cooling. Designing a better battery thermal management system not only needs to be optimized using algorithms on the model but also it uses intelligent algorithms for precise control to achieve safety and reduce energy consumption. This work also reviews the differences in thermal management systems between square and cylindrical batteries and summarizes the development trend of modularity in battery thermal management systems.

“…3 However, Li-ion batteries still have temperature-sensitive thermal safety problems that limit their development and application. Usually, the appropriate range of the working temperature of Li-ion batteries is between 20 and 50 °C, 4 and the temperature difference is controlled to below 5 °C to meet the needs for the optimal performance and lifetime. 5 On the one hand, if the temperature of an automotive Li-ion battery cannot be maintained within the normal range, the excessive battery temperature will produce a series of butterfly effects, which may lead to the spontaneous combustion or even explosion of the vehicle in a short time.…”

Phase change materials (PCMs) are considered the most promising cooling technology due to their high latent heat, good reversibility, and low cost. However, in practical applications, PCMs encounter problems such as a sharp temperature increase after full melting and low thermal conductivity. To solve these problems, a new double helix-type liquid cooling plate is developed and coupled with a hydrated salt composite PCM (CPCM) for battery pack cooling. The modified CPCM has a high latent heat (249 J/g), suitable phase change temperature (35 °C), improved thermal conductivity to 1.86 W/(m·K), and reduced subcooling to 1.9 °C. The design of the liquid cooling plate structure can make the average water temperature on both sides of each cell approximate, thereby ensuring the temperature uniformity for the battery pack. A battery module system test rig is constructed and the heat dissipation effect for the battery module is compared with four cooling methods. The results reveal that the CPCM/liquid coupled cooling method is the most effective for cooling the battery pack. At a low coolant flow rate of 0.5 L/min, the maximum temperature difference for the coupled battery module is retained at 1.88 °C, and the average temperature is found to increase by only 9.6 °C. In addition, different coolant flow rates and control strategies of the coupled heat sink system are tested and compared. An optimal strategy is selected for the cyclic charge/discharge test of the coupled cooling module. The system is found to maintain good cooling performance and temperature uniformity after four charge/discharge cycles, and the highest temperature peak for the battery pack is only 40.3 °C, which is within the normal operating temperature range.
