“…9,26 Notwithstanding the potential advantages of metallic materials as heat transfer additives, there are also several drawbacks, such as oxidative sensitivity and metal particle deposition in composite phase change materials (CPCMs). 8 Ma et al 27 reported a composite phase change material based on EG and Bi-MOF (bisubstituted metal− organic framework), which effectively increased the thermal conductivity of the PCM composite by 735.5% from the original 0.3048 to 2.546 W/(m•K) owing to the addition of EG. Furthermore, Yan et al 28 investigated the thermal properties of an erythritol/EG composite PCM.…”

In recognition of their excellent capacity for regulating thermal energy storage and release, phase change materials (PCMs) have been rediscovered and received growing significance in advanced solar energy storage and battery thermal management (BTM). Nevertheless, their insufficient thermal conductivity, poor shape stabilization, and high rigidity hinder their application in BTM systems. Herein, we reported a novel stable ordinary temperature flexible phase change material (FPCM) basis of paraffin wax (PW), polyolefin elastomer (POE), and expanded graphite (EG), which efficiently solves the aforementioned problem. And then, through flexibility, the FPCM was smartly mounted on the power batteries by overfilling, making the components compact and efficient. Thermal contact resistance (TCR) while operating the battery pack could be decreased by the flexible wrapping of the FPCM. Results show that the above BTM assembly effectively reduced the TCR to 0.28 °C/W. This FPCM-based reactive cooling BTM ensures that the temperature of the battery pack is kept under a safe temperature (55 °C) at all times. With the effect of EG, the prepared FPCM exhibits a substantial improvement in thermal conductivity, achieving 1.929 W/mK, as well as a prominent photothermal efficiency of conversion (91.2%). Notably, its ultraflexibility, high thermal conductivity, and excellent latent heat provide a convenient way for the thermal management packaging of complex and multimodel electronic devices.

Polyimide (PI) aerogels are promising in various fields of application, ranging from thermal insulators to aerospace. However, they are typically in the form of a bulk monolith, which suffers from a lack of conformability and drapability. Moreover, their electrical conductivity is limited, and they mainly display an insulative behavior. These shortcomings can limit the applications of PI aerogels in energy storage systems, which require ultralightweight flexible conductive films, which at the same time offer high thermal stability, ultralow density, and high surface area. To overcome these obstacles, the present study reports the fabrication of PI-carbon nanotube (PI-CNT) aerogel composite films with varying CNT content prepared through a sol−gel preparation method, followed by a supercritical drying procedure. Compared to pristine PI aerogels, which displayed a large shrinkage and density of 18.3% and 0.12 g cm −3 , respectively, the incorporation of only 5 wt % CNTs resulted in a significant reduction of both shrinkage and density to only 11.5% and 0.10 g cm −3 , respectively. This suggests the importance of CNTs in improving the dimensional stability of aerogels and creating a robust network. Further characterizations showed that incorporation of 5 wt % CNTs also resulted in the highest pore volume (1.25 cm 3 g −1 ), highest surface area (324 m 2 g −1 ), highest real permittivity (80), highest electrical conductivity (3 × 10 −1 S m −1 ), and ultrahigh service temperature (575 °C). It was also shown that the aerogel films can withstand a large degree of bending, can be twisted, and can be fully rolled with no obvious cracks propagated in the structure. The combined outstanding properties of the developed aerogel composite films make them promising potential candidates for supercapacitor electrodes. Therefore, the electrochemical performance of the devices based on aerogel electrodes was further studied. The device demonstrated a high energy density of 2.6 Wh kg −1 at a power density of 303.8 W kg −1 . The total capacitance after 5000 cycles was 91.8% of the initial capacitance, which indicated excellent stability and durability of the device. Overall, this work provides a facile yet effective methodology for the development of high-performance aerogel materials for energy storage applications.
