Experimental Analysis on the Thermal Management of Lithium-Ion Batteries Based on Phase Change Materials

Abstract

Temperature is an important factor affecting the working efficiency and service life of lithium-ion battery (LIB). This study carried out the experiments on the thermal performances of Sanyo ternary and Sony LiFePO4 batteries under different working conditions including extreme conditions, natural convection cooling and phase change material (PCM) cooling. The results showed that PCM could absorb some heat during the charging and discharging process, effectively reduce the temperature and keep the capacity stable. The average highest temperature of Sanyo LIB under PCM cooling was about 54.4 °C and decreased about 12.3 °C compared with natural convection in the 2 C charging and discharging cycles. It was found that the addition of heat dissipation fins could reduce the surface temperature, but the effect was not obvious. In addition, the charge and discharge cycles of the two kinds of LIBs were compared at the discharge rates of 1 C and 2 C. Compared with natural convection cooling, the highest temperature of Sanyo LIB with PCM cooling decreased about 4.7 °C and 12.8 °C for 1 C and 2 C discharging respectively, and the temperature of Sony LIB highest decreased about 1.1 °C and 2 °C.

Battery Thermal Management Systems: Current Status and Design Approach of Cooling Technologies

“…A solution could be microencapsulation, but high costs [96], the required laborious procedures [97] and the change in volume during temperature variations [98] reduce its applicability. Chen et al [99] proposed a PCM with high thermal conductivity and a solid-solid phase change, enhanced with fins to further increase thermal performance. Lv et al [100] developed a paraffin-based CPCM with improved anti-leakage and anti-volume-change properties, obtained by adding nanosilica into the CPCM, conform the schematics from Figure 8a.…”

Special Issue “Advanced Phase Change Materials for Thermal Storage”

“…The third paper accepted in this special issue introduced the use of PCMs for the thermal management of lithium-ion batteries (LIBs), since temperature is an important factor affecting the working efficiency and service life of these devices [3]. In this work, the authors studied the thermal performance of two commercial batteries (Sony and Sanyo) under different working conditions: extreme conditions (inside a closed aluminum tube), natural convection cooling and PCM cooling with and without heat dissipation fins.…”

Experimental study on the hybrid carbon based phase change materials for thermal management performance of lithium‐ion battery module

“…Phase change cooling have broad application prospects in the thermal management of EV on account of its merits of no additional energy consumption, reduced moving parts, reduced volume of the entire battery system, great temperature control effect, etc. Therefore, scholars have done a lot of work on the application of PCM 21‐23 . To overcome the inherent shortcomings of pure PCM and let it be fitting for practical uses, a great deal of work has been done to develop advanced PCM.…”
