Study on High Energy Storage Dielectric Capacitor

With the continuous consumption of energy, more and more energy storage devices have attracted the attention of researchers. Among them, dielectric capacitors have the advantages of high power density, fast charging and discharging efficiency, long cycle life and good reliability, which can be widely used in new energy, electronic equipment and other fields. However, the energy density of dielectric capacitors is not high, so it is important to study dielectric capacitors with high energy storage density. The performance of dielectric capacitors is related to dielectric materials. Therefore, dielectric materials with excellent dielectric properties have been widely studied. In this paper, the research on high energy storage dielectric capacitors in recent years is reviewed, and the performance of these materials is analyzed.
