“…Modern AC capacitors are usually wound using biaxially oriented polypropylene (BOPP) rolls in combination with thin aluminum foil. Depending on the application, other polymers, such as polyethylene (PE), polystyrene (PS), polypropylene (PP), polycarbonate (PC), Polyethylene naphthalate (PEN), Polyphenyl sulfide (PPS), polytetrafluorethylene (PTFE), polyester imides (PEI), polyethyleneterephthalate (PET), polybutyleneterephthalate (PBT), polyetheretherketone (PEEK), polyvinylchloride (PVC), polyvinylidene fluoride (PVDF), polyimides (PI), polyamides (PA) and polymethylmethacrylate (PMMA) can be used [ 7 , 9 , 11 , 27 , 28 , 29 ].…”

High-voltage capacitors are key components for circuit breakers and monitoring and protection devices, and are important elements used to improve the efficiency and reliability of the grid. Different technologies are used in high-voltage capacitor manufacturing process, and at all stages of this process polymeric films must be used, along with an encapsulating material, which can be either liquid, solid or gaseous. These materials play major roles in the lifespan and reliability of components. In this paper, we present a review of the different technologies used to manufacture high-voltage capacitors, as well as the different materials used in fabricating high-voltage film capacitors, with a view to establishing a bibliographic database that will allow a comparison of the different technologies

“…Alternative technologies in the energy generation sector, miniaturization in the electronics industry, and electric mobility have opened up many doors for advancements in the field of energy storage [1]. Due to the high dielectric strength, various dielectric polymers, such as polypropylene, polycarbonate, and polyethylene terephthalate, were commercially used for decades in thin film and thick film capacitors, all showing a linear dielectric response and thus a plain capacitive behavior [2][3][4]. For a non-linear or hysteretic material, the stored energy density in a polarization-electric field graph is given by the area between the charging branch of a dielectric displacement-electric field hysteresis loop and the dielectric displacement axis (Figure 1).…”

The temperature dependence of the dielectric permittivity and polarization hysteresis loops of P(VDF-TrFE-CFE) polymer films with different compositions are studied. Among them, the three compositions, 51.3/48.7/6.2, 59.8/40.2/7.3, and 70/30/8.1, are characterized for the first time. Relaxor behavior is confirmed for all studied samples. Increasing the CFE content results in lowering the freezing temperature and stabilizes the ergodic relaxor state. The observed double hysteresis loops are related to the field-induced transition to a ferroelectric state. The critical field corresponding to this transition varies with the composition and temperature; it becomes larger for temperatures far from the freezing temperature. The energy storage performance is evaluated from the analysis of unipolar polarization hysteresis loops. P(VDF-TrFE-CFE) 59.8/40.2/7.3 shows the largest energy density of about 5 J·cm−3 (at the field of 200 MV·m−1) and a charge–discharge efficiency of 63%, which iscomparable with the best literature data for the neat terpolymers.

“…The polymer capacitor is a typical example of a physical battery. Compared to the rechargeable lithium batteries, the polymer capacitors show very low energy density (∼ 0.1 Wh/kg) and significantly higher power density [5][6][7]. Due to the mentioned characteristics, the polymer capacitors are used primarily in low-energy electronics, they can also be easily designed for high-voltage applications.…”

The price and environmental aspects of electricity storage significantly affect the application of green technologies. The electrochemical batteries are currently the best choice for storing electricity for most industrial needs and products. Polymer capacitors show very low energy density compared to conventional batteries and therefore cannot be widely used for electricity disposal. At the same time, all other features of polymer capacitors that characterize battery systems are ideal. After a brief comparison of the basic properties of electrochemical and physical batteries, this paper presents the influence of electron trapping on the energy density of a polyethylene capacitor. The presented results indicate that the phenomenon of electron trapping in polymers can increase the energy deposit of polymer capacitors.
