The electric heating film systems (EHFS) have recently attracted much attention as a clean and low-carbon building heating way due to the global target of carbon neutrality. This paper aims to provide a comprehensive review of the materials, performances and applications of the electric heating film (EHF).
(1) Currently, there is a lack of scientific reports dealing with the integration of flexible thick-film structures (film thickness of at least several μm) for energy storage. To date, there is only one report on the fabrication of thick films for energy storage.
The introduction of highly polar groups into the polymer chain and the incorporation of high- k inorganic fillers are usually utilized to develop dielectric film with high energy storage performance.
The 0.1 wt% composite film maintains outstanding high-temperature energy storage capability at 150 °C, e.g. the energy density of 8.6 J/cm 3 with the charge-discharge efficiency of 91.2 % at 475 MV/m.
Such high electric fields, high polarization, and low hysteresis losses result in promising energy-storage properties. In annealed films, the recoverable energy density reaches 10 J·cm –3 and an energy storage efficiency of 73% (at 1000 kV·cm –1 ).
Even at 200 °C, it retains a U90 of 3.15 J cm −3. Furthermore, its robust high-temperature storage modulus, reproducibility, and reliability offer promising potential for future applications. Polymer-based film capacitors are increasingly demanded for energy storage applications in advanced electric and electronic systems.
