“…Except excellent thermal stability and reliability, HNTs-GA skeleton endows the system with considerate light-to-thermal (η=75.6 %) and electro-tothermal (η=67.2 %) conversion. Besides serving as skeleton, in Wei's work [161] , via a combination of pre-refrigeration and freeze-drying techniques, graphene was reported to be filler to modify cellulose matrix. Interestingly, with only 1.51 wt.% of graphene, high thermal conductivity (1.03 W/m K) was obtained and the SSPCMs display simultaneously light-tothermal and electro-to-thermal behaviors, the study cut down on the usage of graphene which greatly reduces the cost of manufacture.…”

Organic phase change materials (OPCMs) are advanced energy storage materials with ability to storage and release thermal energy at constant temperature. Efficient energy storage systems using shape-stabilized PCMs (SSPCMs) are promising to adjust the gap between energy supply and demand. The performances of SSPCMs are influenced by multiple factors which are necessary to be considered in the fabrication process. In this regard, we summarized the desired properties for OPCMs and SSPCMs, then we systematically discussed the fabrication methods involving supporting materials, OPCMs and fillers. At last, we elaborated thermal storage applications of SSPCMs from three kinds of energy sources. This review intends to provide in-depth and constructive insights into the fabrication and energy storage applications of SSPCMs, thereby contributing to development and application of high-performance SSPCMs.

“…SA could be well shape‐stabilized into the obtained 3D HPC through capillary force and surface tension. [ 99–137 ] The interconnected 3D network structure provided sufficient space to freely stretch and crystallize SA molecules and continuous channels for phonon transfer. [ 24 ] In addition, the interactions between SA and rGO considerably reduced the interfacial thermal resistance, thereby accelerating the transmission of phonons.…”

Phase change materials (PCMs) can alleviate concerns over energy to some extent by reversibly storing a tremendous amount of renewable and sustainable thermal energy. However, the low thermal conductivity, low electrical conductivity, and weak photoabsorption of pure PCMs hinder their wider applicability and development. To overcome these deficiencies and improve the utilization efficiency of thermal energy, versatile carbon materials have been increasingly considered as supporting materials to construct shape‐stabilized composite PCMs. Despite some carbon‐based composite PCMs reviews regarding thermal conductivity enhancement, a comprehensive review of carbon‐based composite PCMs does not exist. Herein, a systematic overview of recent carbon‐based composite PCMs for thermal storage, transfer, conversion (solar‐to‐thermal, electro‐to‐thermal and magnetic‐to‐thermal), and advanced multifunctional applications, including novel metal organic framework (MOF)‐derived carbon materials are provided. The current challenges and future opportunities are also highlighted. The authors hope this review can provide in‐depth insights and serve as a useful guide for the targeted design of high‐performance carbon‐based composite PCMs.

“…As previously mentioned, the array-oriented structure exhibits more potential in electro-thermal conversion of PCMs. Based on this design concept, Wei et al (2019) prepared microcrystalline cellulose (MCC)/GNPs aerogel with a highly arrayoriented framework using a pre-refrigeration and freeze-drying method (Figure 10A). The introduction of GNPs facilitates the formation of porous anisotropic structure (Figures 10B and 10C).…”

Advanced functional electro-thermal conversion phase change materials (PCMs) can efficiently manage the energy conversion from electrical energy to thermal energy, thereby playing a significant role in sustainable energy utilization. Considering the inherent insulating properties of pristine PCMs, electrically conductive supporting materials are widely used to encapsulate PCMs to prepare composite PCMs for electro-thermal conversion and storage. Herein, we comprehensively review the recent advances in different electro-thermal conversion PCMs, mainly including carbon-based PCMs (carbon nanotubes [CNTs], graphene, biomass-derived carbon, graphite, highly graphitized carbon, and metal organic frameworks [MOFs]-derived carbon) and MXene-based PCMs. This review aims to provide an in-depth understanding of the electrothermal conversion mechanism and the relationships between structure design (random and array-oriented structure or single and hybrid supporting materials) and electrothermal properties, thereby contributing profound theoretical and experimental bases for the construction of high-performance electro-thermal conversion PCMs. Finally, we highlight the current challenges and future prospects.
