<p>High-temperature film capacitors have been widely used in numerous applications, such as energy storage components in hybrid electric vehicles, smart grid, and pulsed power sources. The commercial film capacitors fabricated...</p>

Study on the Preparation and Properties of Several Dielectric Composites Applied to Capacitors

“…The breakdown strength of the three composites slowly decreased with the increase in filler amount. The maximum energy storage density of 1.81 J/cm 3…”

“…In recent years, with the development of the electronics industry, electronic components have attracted considerable attention [1,2]. Among them, dielectric capacitors are widely concerned because they can be used in many fields such as new energy and aerospace [3]. The dielectric materials determine the properties of the dielectric capacitors [4].…”

Dielectric polymers for high-temperature capacitive energy storage

“…13b), which shows a high K of 4.6 at room temperature and 1 kHz that is stable up to T g (i.e., 128 °C ). 182 Interestingly, ABS exhibits an excellent highfield performance even near its T g , which is rarely seen in amorphous dielectric polymers. As shown in Fig.…”

High-temperature dielectric polymer composite films of all-organic PVDF/ABS with excellent energy storage performance and stability

“…For ABS, both the e r and tan d remain invariable before reaching its high glass transition temperature (T g : 128 1C), however, above T g , they increase quickly caused by the ionic conductivity, indicating that the ABS film has high dielectric stability below T g . 12 Conversely, the e r and tan d of PVDF change obviously, indicating the poor temperature resistance because of the enhanced mobility of impurity ions as the temperature increases. 23 Interestingly, the PVDF/ABS-40% exhibits favorable temperature toleration for maintaining low tan d (B0.04) over a wide temperature range from 30 1C to 130 1C at 1 kHz.…”
