“…Because of its compact structure and good thermal management performance, the liquid cooling system has been widely used in a lithium-ion BTMS. , However, the liquid cooling system requires high sealing performance of the battery pack; the design of the cooling system is complicated; and it is difficult to meet the requirement of uniformity of the internal temperature distribution inside the battery module . In comparison to a single cooling system, the cooling effect of coupling a lithium-ion BTMS is undoubtedly better, but structural compactness and financial issues are also important factors to be considered in the design of a lithium-ion BTMS. − …”

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.

“…Once the center temperature ramped up to 40 C, the liquid system started to work, while it turned off if the center temperature fell below 35 C. Their results indicated that the controllable strategy could prevent frequent start-stop to some extent, thus reducing pump consumption by about 60%. In 2022, Chen et al [154] presented a gradient layout for cylindrical batteries, which placed PCMs with different EG content along the flow direction. Then, they further applied a delayed liquid cooling for 4 C discharge and 1 C charge cycles.…”

Recent Developments of Thermal Management Strategies for Lithium‐Ion Batteries: A State‐of‐The‐Art Review

2022

View full text Add to dashboard Cite

The performance of lithium‐ion batteries is quite dependent on temperature and a series of investigations on the battery thermal management system (BTMS) have been reported during the past decades. Herein, the recent developments of BTMS are thoroughly summarized. First, the thermal characteristics of the battery caused by different temperature conditions and temperature nonuniformity are described. Then, the thermal models, including electro‐thermal coupled model and electrochemical–thermal coupled model are briefly presented. Subsequently, various traditional strategies like air cooling, liquid cooling, phase change material (PCM) cooling, and heat pipe cooling are elaborated. With the development of battery technology, BTMS based on a single strategy alone cannot meet the growth of thermal requirements, especially under dynamic and high‐power energy conditions. Hence, a hybrid BTMS that integrates two or more cooling strategies begins to be studied and provide a feasible solution for the problem. The related studies on hybrid BTMS are also systematically reviewed from the perspective of combinations, such as air–PCM, liquid–PCM, heat pipe–PCM, and other hybrid strategies. Besides, the current research on battery preheating strategies is also summarized. Finally, insufficient present studies are pointed out, aiming to provide comprehensive guidance toward the development of battery thermal management.

Structural Analysis of Phase Change Materials (PCMs)/Expanded Graphite (EG) Composites and Their Thermal Behavior under Hot and Humid Conditions

Expanded graphite (EG) has been used to store phase change materials (PCM) to enhance thermal conductivity and avoid leakage. However, systematic investigation on physical structure of various embedded PCMs in EG is not reported. Besides, the effect of environment on thermal behavior of PCM/EG composites has not been investigated yet. In this work, three common PCMs (including myristic acid (MA), polyethylene glycol (PEG) and paraffin wax (PW)) were embedded in EG and three PCM/EG composites were obtained. As a result, capillary force between EG and PCMs supported encapsulation of PCMs in EG. PCM/EG composites had narrower phase change range while supercooling degree values were different when various PCMs were used. Besides, the hot and humid environment had a side effect on thermal energy storage of PCMs and PCM/EG composites. The inherent hydrophilicity of PCMs was essential for resistance against side effect of moisture on thermal energy storage.
