Electric mobility decarbonizes the transportation sector and effectively addresses sustainable development goals. A good battery thermal management system (BTMS) is essential for the safe working of electric vehicles with lithium‐ion batteries (LIBs) to address thermal runaway and associated catastrophic hazards effectively. However, PCMs suffer from low thermal conductivity issues, and hence, enhancement techniques include the use of fins, nano‐additives, extended graphite powder, and so forth. The use of composite phase change materials effectively addresses LIB thermal management widely used in electric vehicles while mitigating thermal runaway, besides providing flame retardancy, thermal/mechanical stability, and electrical insulation, and preventing leakage. It is noted that no single strategy of BTMS is brought down to a safe zone of temperature, and hybrid BTMSs are being employed, invariably involve phase change materials (PCMs) to a large extent. It is essential to utilize CPCMs to address the effects of low‐temperature environments and vibrations considering vehicle driving cycles and operating conditions. It is observed from the review that ultrasonic monitoring and early detection of internal short circuits are the steps towards mitigation of thermal runaway propagation. It is required to utilize optimization methods, machine learning and IoT tools for a feasible PCM based BTMS work. Present review briefly describes potential methods for effective utilization of PCMs, comparison among different methods, challenges associated and potential solutions. It is highly essential to develop compact and economical BTMS with effective CPCMs for better and safer LIB operation to attract large‐scale commercialization of electric vehicles.

“…The main drawback of PCMs, such as paraffin, is the low thermal conductivity, which goes against heat dissipation and absorption. [ 177 , 178 ] One promising solution to this drawback is the addition of expanded graphite, graphene or metals to PCMs to improve their thermal conductivity. [ 179 ] Compared to paraffin, more cost‐effective sodium thiosulfate pentahydrates (STP) are advantageous in higher thermal conductivity and an appropriate melting point (47 °C) within desired battery operating temperature range.…”

High energy and power density alkali‐ion (i.e., Li+, Na+, and K+) batteries (AIBs), especially lithium‐ion batteries (LIBs), are being ubiquitously used for both large‐ and small‐scale energy storage, and powering electric vehicles and electronics. However, the increasing LIB‐triggered fires due to thermal runaways have continued to cause significant injuries and casualties as well as enormous economic losses. For this reason, to date, great efforts have been made to create reliable fire‐safe AIBs through advanced materials design, thermal management, and fire safety characterization. In this review, the recent progress is highlighted in the battery design for better thermal stability and electrochemical performance, and state‐of‐the‐art fire safety evaluation methods. The key challenges are also presented associated with the existing materials design, thermal management, and fire safety evaluation of AIBs. Future research opportunities are also proposed for the creation of next‐generation fire‐safe batteries to ensure their reliability in practical applications.

The demand for thermal management materials is growing due to the rapid development of electronics. However, most thermally conductive composites cannot be recycled after use, resulting in a significant waste of resources and environmental pollution. In this work, a recyclable and reprocessable high thermally conductive epoxy resin composite is developed by utilizing biobased raw materials epoxidized soybean oil (ESO). The recyclability and reprocessability are achieved by disulfide exchange. The thermal conductivity of the matrix is improved by adding boron nitride (BN) fillers, which are further compelled to be aligned in the matrix to fabricate a highly thermally conductive bulk epoxy composite in an oriented direction. Results reveal that a thermal conductivity of 3.01 W m −1 K −1 is achieved in the composites with aligned arrangement BN, which is increased by 32.6% compared to composites with randomly distributed filler. Moreover, due to the disulfide exchange, the matrix can be decomposed under chemical conditions, which allows for the filler to be completely separated through physical filtration for reuse, completing the closed-loop recycling of the filler. This study provides an effective and facile method for the fabrication of biobased thermal management materials and also offers paramount potential for sustainable development.
