Advanced Engineering Materials for Enhancing Thermal Management and Thermal Safety of Lithium-Ion Batteries: A Review

Abstract

Lithium-ion batteries (LiBs) are the key power source for electric vehicles (EVs). Battery thermal management system (BTMS) is essential to ensure safety and extend service life of LIBs. This paper reviews the various refrigeration materials used in the BTMS in EVs, including liquid coolant, phase change material (PCM). The thermal properties of these refrigerant materials are summarized and the innovative ways to improve the cooling efficiency of the BTMS are analyzed. The various ways to enhance the battery’s thermal performance by modifying the materials of the electrode, separator, and electrolyte are also reviewed. Finally, the research prospect in area of BTMS is summarized. This review will inspire new BTMS design and further improvement in battery safety and performance with the aid of advanced intelligent technologies.

A review of Li‐ion battery temperature control and a key future perspective on cutting‐edge cooling methods for electrical vehicle applications

“…The sort of coolant must be used to keep the battery from corroding. The variety of coolants available is likewise severely limited 76 . Additionally, the fluid must be circulated at a significant additional power requirement to achieve the appropriate flow rate, which raises the vehicle's overall energy consumption 77 .…”

“…The variety of coolants available is likewise severely limited. 76 Additionally, the fluid must be circulated at a significant additional power requirement to achieve the appropriate flow rate, which raises the vehicle's overall energy consumption. 77 A parametric analysis was carried out by Patil et al 78 to assess the thermal performance of several U-turn type microchannel cold plates.…”

Fluorinated co-solvent electrolytes for high-voltage Ni-rich LiNi0.8Co0.1Mn0.1O2 (NCM811) positive electrodes

“…Nowadays, lithium-ion batteries (LIBs) are the important power sources for portable electronics, electric vehicles, aerospace, and deep-sea diving devices due to their high energy density, acceptable cycle life, and no memory effect (Wang et al, 2020;He et al, 2021). With the continuous expansion of the application fields of LIBs, lots of efforts have been made to further improve their energy density and safety (Leach et al, 2022;Li et al, 2022;Yang et al, 2022). So far, Nickel-rich LiNi x Co y Mn 1-x-y O 2 (NCM for short, x ≥ 0.6) materials, specially, Nickel-rich LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811 for short) positive electrodes are one of the most promising positive electrodes for utilization in the next-generation of lithium-ion batteries (Li et al, 2020;Xue et al, 2021).…”
