Porous-Material-Based Composite Phase Change Materials for a Lithium-Ion Battery Thermal Management System

Abstract

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.

Robust Smart Fabrics Composed of MgO Nanostructures Encapsulated in Hollow Polystyrene Fibers for Efficient Thermoregulation

“…ER and EE increase with the increased LA loading, and LA/PW-50% shows a higher ER value of over 70%, which is comparable to other work. , The thermal conductivity of PCMs is tested, and the results are shown in Figure f. The measured thermal conductivity of pure PW and LA is 0.25 and 0.45 W/mK, respectively, which is in good agreement with the reported literature. , Thus, it is not surprising to see that the thermal conductivity of CPCM falls between 0.26 and 0.31 W/mK. After analyzing the advantages and disadvantages of all CPCMs, LA/PW-50% is selected to prepare the fabric.…”

“…24,25 LA with the melting temperature falling between 40 and 44 °C is employed to adjust the melting point of CPCM, and its latent heat is 211.6 J/g. 26 The optimization essence is to find the best ratio between these two materials, maintaining a comparable latent heat, suitable phase change temperature, and favorable antileakage properties.…”

“…Therefore, guaranteeing unsafe scenarios, such as electrolyte leakage and toxic heavy metals, should be strictly limited. Mild and non-toxic FSBs are a trend of the future. , In addition to the electrochemical performance, the practical fabrication and encapsulation process, durability, etc. will be other major considerations with the increasing popularity of energy textiles.…”

“…A large amount of research work is currently devoted to the development of advanced battery thermal management systems (BTMSs), which can be divided into several categories, namely, air-cooled, , liquid-cooled, , heat pipes, , and phase change material (PCM)-cooled systems. , The air-cooled system has the advantage of simple structure and low cost and is one of the traditional thermal management methods for Li-ion batteries. The current studies on air cooling are primarily focused on structural optimization, such as the determination of the air inlet and outlet locations, , arrangement of air-cooled channels, study of the overall control strategy of the air-cooled device, and study of the airflow state .…”
