“…Among all photothermal dopants, the carbon‐based solar‐thermal structures that are considered ideal are the ones that simultaneously allow for both harvesting of broadband solar energy and improving the thermal conductivity of composite PCMs 30a,155. Several carbon structures, including graphene sheets, graphene foam,155c CNTs, CNT sponge, and graphite, have been composited with PCMs to achieve solar‐thermal energy harvesting and storage.…”

Thermal energy storage technologies based on phase‐change materials (PCMs) have received tremendous attention in recent years. These materials are capable of reversibly storing large amounts of thermal energy during the isothermal phase transition and offer enormous potential in the development of state‐of‐the‐art renewable energy infrastructure. Thermal conductivity plays a vital role in regulating the thermal charging and discharging rate of PCMs and improving the heat‐utilization efficiency. The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically. Furthermore, a research perspective is given to highlight emerging research directions of engineering advanced functional PCMs for energy applications.

Flexible electro-thermal heating film has caught great attentions for their efficient energy conversion and easy to customization in many fields. In this work, an ultrafast electro-thermal responsible heating film was fabricated via silk-screen printing method by using graphene modified carbon black based conductive ink. The graphene modified carbon heating film (CHF) was able to reach an equilibrium-state temperature with rapid o o o o heating and cooling rate of 5.6 C/s and 15.6 C/s, comparing to the unmodified sample (1.01 C/s and 1.03 C/s), for the high electrical and thermal conductivity and huge heat exchanging area. The steady temperature of CHF was controllable by changing the amount of graphene. A o dramatic enhancement of steady temperature from 38 to 83 C was controlled by changing graphene amount from 0 to 35 wt.%. The facile fabrication and superior electro-thermal performance of CHF make it feasible to scale up and customization for various heating conditions.

“…Recently, filling up the inner space of nanocarbons with phase change materials (PCMs) [ 8–9 ] shows great potential in reducing the solid–air interface interactions between the nanocarbons and surrounding air because redundant heat can be simultaneously accumulated and released by PCMs. For instance, thermal energy of CNTs sponges based composite PCMs [ 8 ] can be triggered by a low operation voltage of 1.5 V. 3D architecture of CNTs sponges reduces the resistivity, and ensures a low operation voltage.…”

“…Thus, electro‐thermal storage efficiency of CNTs sponge based composite PCMs was 40.6%. Then, ordered anisotropic CNTs array [ 9c ] was developed for electro‐thermal PCMs. The ordered array structure of CNTs array significantly reduces the resistivity of the composite, consequently thermal energy of such composite PCMs can be triggered by 1.3 V. Moreover, less CNTs exposed on the surface of the composite which reduces the convective heat dissipation between CNTs and air.…”

“…Thus, the electro‐thermal storage efficiency was enhanced to 74.7%. Recently, GO/CNTs hybrids alkanes microcapsule [ 9e ] have been developed to eliminate the convective heat dissipation of the joule heating system. The microcapsule protector prevents precocious convective heat dissipation, and the CNTs minimize the electrical conductivity degradation of the system.…”

Electro‐thermal phase‐change materials (PCMs) enable continuous operation of heating‐related processes, which is urgently required for modern thermal‐management devices. Driven by the unmet needs to develop promising electro‐thermal PCMs with low operation voltage and high electro‐thermal storage efficiency simultaneously, unique ZIF@MOF‐derived carbon‐nanotube (CNT)‐penetrated porous carbon supports for electro‐thermal PCMs are introduced. The network structure of the support decreases the resistivity of the composite and ensures a low operation voltage. Furthermore, abundant CNT cores in porous carbon shells facilitate interfacial interaction between the PCMs and the support and realize a rapid heat transformation. It is noted that low thermal conductive porous carbon shells prevent convective heat dissipation at the CNT‐air interface to a great degree which leads to enhanced electro‐thermal storage efficiency. Consequently, the obtained electro‐thermal PCMs exhibit a low operation voltage of 1.1 V and a record‐high electro‐thermal storage efficiency of 94.5%, which shows great potential in thermal management of electronic devices.
