“…Their high energy density and long cycle life have made them a preferred choice over traditional lead-acid and nickel-cadmium batteries. The journey of lithium battery development traces back to the 1970s when they were first introduced [2] . Since then, significant advancements have been achieved, gradually replacing older battery technologies due to their lighter weight and higher efficiency.…”

In view of the problem of heat accumulation in electronic devices, the development of new composites with high thermal conductivity (TC) is the current research focus. Nowadays, improving TC often lead to inevitable deterioration of the mechanical properties of materials. In this work, the E‐functionalized boron nitride nanosheets (f‐BNNS)/liquid crystal monomer (LCM)/Epoxy‐thiol films with high TC were prepared by using flexible epoxy‐thiol polymer as matrix and LCM and f‐BNNS as thermal fillers via high voltage orientation molding. The epoxy‐thiol polymer possessed high intrinsic TC due to the regular arrangement of molecular chains and the f‐BNNS showed favorable dispersibility because of the modification by isopropyl tri(dioctylpyrophosphate) titanate (ITDPT). The results show that TC of E‐f‐BNNS/LCM/Epoxy‐thiol films with 30 wt% f‐BNNS content achieves 1.65 W/m·K and is 511.11% higher than that of pure epoxy‐thiol polymer (0.27 W/m·K). The tensile strength and elongation at break increase to 24.9 MPa and 47.41%, respectively. The favorable results are attributed to the ordered arrangement of f‐BNNS and molecular chains, resulting from the hydrogen‐bonding interaction between OH group in f‐BNNS, LCM and epoxy‐thiol polymer. This research provides a simple and feasible method for preparing flexible epoxy polymer films with high TC.Highlights The functional BNNS was achieved by isopropyl tri(dioctylpyrophosphate) titanate. Effects of matrix thermal conductivity on films thermal conductivity are probed. High voltage orientation molding are used for preparing epoxy composite films. The films demonstrate excellent thermal conductivity and favorable tensile strength.

“…Shen et al 9 reviewed various measures to enhance the thermal performance of PCM‐based systems, thus demonstrating its feasibility and potential to use for thermal management of batteries. Zhang et al 10 introduced a new parameter and investigated the effect of PCM dosage on battery temperature in a PCM‐based BTMS, and suggested a dosage value of 0.75 to 1 for managing battery temperature in a single discharge operation. Ping et al 11 investigated a BTMS scheme coupled with PCM and liquid pipe.…”

Summary The performance, lifetime, and safety of electric vehicles (EVs) are highly reliant on the battery's capacity and temperature. Battery thermal management system (BTMS) involves techniques to control the battery's thermal behavior by maintaining temperature and temperature uniformity within an optimal range. Air cooling BTMS is frequently used in EVs due to its design simplicity and cost‐effectiveness. Only limited works have utilized passive convective heat transfer enhancement strategies for air‐cooled BTMS, especially fin‐based structures for cylindrical lithium‐ion battery packs. Present work introduces a novel design by incorporating the interrupted fins into a conventionally air‐cooled BTMS. The proposed design offers superior heat transfer efficiency as well as ease of manufacturing when compared to the existent herringbone fin design used in prior air‐cooled BTMS literature. Results indicate that the average temperature of the cells and maximum temperature difference were reduced by 5.646 and 7.958 K, respectively, by incorporating an optimal uniform interrupted fin arrangement. The average temperature of the cells was reduced by 0.479 K when the interrupted fins were added to increase the area, compared to 0.088 K for an equivalent area enhancement in a conventional fin. The uniform interrupted fin improved the temperature uniformity by 5.05%, but the area enhanced conventional fin deteriorated it by 1.59%. The non‐uniform interrupted fin arrangement, resulted in an improvement of 4.47%, over uniform interrupted fins, in the battery pack's temperature uniformity.
