“…[7][8][9] Qi et al proposed a hydroxylation method, resulting in a phase change enthalpy of the molten salt composite PCM reaching 355.52 J g −1 . 10 Shuai et al utilized porous silicon carbide ceramics and solar salt to form a composite PCM, resulting in a more uniform temperature distribution during phase change, with the maximum temperature difference reduced from 148 °C to 130 °C, and an overall phase change rate increased by 42.9%. 11 However, due to the limitations in electrical conductivity and shape stability of molten salt PCM, heat storage is typically achieved through indirect electrical heating (IEH).…”

Phase change materials (PCM) often encounter severe problems of leakage and shape collapse concerns. Chemical modification methods, utilizing chemical bonds to bind phase change molecular chains, have the potential to address the above‐mentioned problems radically. However, this approach often entails the use of expensive raw materials and complex processes. Therefore, a simple one‐pot preparation method had been reported using earth‐abundant and inexpensive octadecyl methacrylate (OMA) and 1,6‐hexanediol diacrylate (HD) as raw materials to prepare PCM with a molecular structure of cross‐linked polymer main chains and phase change side chains through free radical polymerization. Owing to the three‐dimensional polymer main chain structure, it exhibited excellent leakage‐proof performance, maintaining its form‐stable nature at 70°C with no obvious leakage observed during the phase change process, confirming it to be an excellent intrinsic solid–solid PCM (SSPCM). Additionally, the introduction of the cross linking segment significantly improves its thermal stability, and the 50% degradation temperature increased significantly from 228.8 to 355.9°C. Moreover, the latent heat increased with the decrease of the crosslinking density until the molar ratio of HD/OMA was reduced to 1/40 and then tended to reach constant. At the optimal ratio the latent heat of SSPCM can reach 88.23 J g−1. Excessive crosslinking density will affect the stacking tightness of molecular chains during the crystallization process, thereby reducing the latent heat.

Battery thermal management system (BTMS) based on phase change materials (PCMs) is simple in structure while presenting outstanding performance, but the core bottleneck hindering the industrialization of which is the poor performance of PCMs’ pivotal properties. Apart from that, under extreme conditions, single passive phase change temperature‐control technology apparently could not meet the demands. Therefore, modification strategies to improve PCM's pivotal properties suitable for BTMS are thoroughly reviewed. Moreover, the optimization of as‐mentioned passive systems by integrating them with other active heating or cooling devices to obtain advanced active and passive full‐temperature responsive capability is also summarized. Profound opinions concerning about the prospect and challenges of PCM‐BTMS are given. It is expected to provide some innovative ideas for the advancement of such promising technology.
