“…Metal copper is a good heat conductor, with a thermal conductivity as high as 401 W m −1 K −1 . Wu et al embedded a copper mesh into the PCMs to increase their thermal conductivity . At a discharge rate of 5 C, the maximum temperatures of the battery modules with and without copper mesh were 61.6 and 65.5 °C, respectively, showing that the structure has a better heat dissipation capability and a smaller temperature difference between the battery modules than the copper‐free network.…”

Thermal energy storage technologies based on phase‐change materials (PCMs) have received tremendous attention in recent years. These materials are capable of reversibly storing large amounts of thermal energy during the isothermal phase transition and offer enormous potential in the development of state‐of‐the‐art renewable energy infrastructure. Thermal conductivity plays a vital role in regulating the thermal charging and discharging rate of PCMs and improving the heat‐utilization efficiency. The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically. Furthermore, a research perspective is given to highlight emerging research directions of engineering advanced functional PCMs for energy applications.

[1][2][3][4][5][6][7][8][9] Commonly used PCMs are alkanes, paraffin, fatty acids, and polyols. As a promising type of organic PCMs, fatty acid, where general type is CH 3 CH 2n COOH, has been broadly investigated owing to their large thermal energy storage (TES) capability and reasonable thermal properties, such as large latent heat, good thermal stability, little supercooling or nonsupercooling, and low cost.…”

Summary Using palmitic acid (PA) as an organic phase change material (PCM), a series of PA/diatomite composite PCMs (CPCMs) composed of PA absorbed into diatomite mesopores with different mass contents were made through direct impregnation method. Nitrogen adsorption‐desorption curves indicated the porous structure of diatomite with the specific surface area and the mesopore peak at 40 m2/g and 3 to 5 nm, respectively. The form‐stability measurement indicated that the maximum mass loading capacity of PA was 55 wt%. The melting temperature and fusion enthalpy of the PA/diatomite CPCM (55 wt%) were calculated from DSC at 63°C and 88 J/g, respectively. The thermal cycle test implied that the PA/diatomite CPCM with 55‐wt% PA loading showed excellent thermal reliability after 1000 thermal cycles. Moreover, the composite has thermal conductivity at 0.5810 W/m·K and enhanced thermal storage/release rate. PA/diatomite CPCM (55 wt% PA) was a suitable candidate for modern building energy saving and industrial solar energy.

“…The thermal management performance of PCM/expanded graphite at low temperature were studied by Ling et al, 11 and the results showed that with the lower-thermal conductivity, the temperature-dropping process would be extended, as our previous work reported. 12 Furthermore, the nickel foam, 13 Graphene-coated nickel foam, 14 expanded graphite, 15 and copper foam 16,17 were employed in BTM as well.…”

Summary With the latent heat, the phase change material (PCM) is widely used in battery thermal management (BTM) to control the temperature. In this paper, the porous medium is employed to enhance the heat transfer of PCM. The lattice Boltzmann model for PCM/porous medium in pore scale is considered, where the mesh system with porous medium (fixed point) is generated by quartet structure generation set (QSGS) method. The effects of the Rayleigh number and porosity on the heat transfer process in BTM are investigated. The results show that decreasing the porosity will accelerate the melting rate. When the porosities are 0.9, 0.8, 0.7, and 0.6, the total melting times are decreased by 23.7%, 43.3%, 58.0%, and 75.4%, compared with pure PCM. The heat is transferred through the high‐conductivity framework. The natural convection in the porous medium is weak, and the conduction is the dominated heat transfer. As a result, the area of solid–liquid interface will be increased, and the heat‐transferred rate is accelerated. However, when the Rayleigh number is raised to 105, applying the porous medium with porosity of 0.9 will increase the total melting time, resulted from the stronger natural convection of PCM. The present study is helpful for design of PCM/porous medium‐based BTM.
