High-entropy (HE) ceramic capacitors are of great significance because of their excellent energy storage efficiency and high power density (PD). However, the contradiction between configurational entropy and polarization in traditional HE systems greatly restrains the increase in energy storage density.
Dielectric capacitors with a ceramic base are crucial energy-storage components in modern electronic and electrical power systems. Ceramic-based dielectrics have been demonstrated to be the most promising choices for energy-storage applications, as shown throughout this study and summarized in Figure 4.
Along with the rapid development of electrostatic capacitors requiring dielectric materials to exhibit environmental-friendly and outstanding performance, numerous efforts have been made to enhance the energy storage properties of lead-free ceramics for pulsed power capacitor applications in recent reports , , , .
The failure of ceramic capacitors during dielectric breakdown, which renders the device worthless, is another pertinent component of these devices . For power devices, Cer-aLinkTM, a new ceramic capacitor technology from EPCOS, may be the ideal option.
High electric breakdown strength and high maximum but low-remnant (zero in the case of linear dielectrics) polarization are necessary for high energy density in dielectric capacitors. The high performance, multi-functionality, and high integration of electronic devices are made possible in large part by the multilayer ceramic capacitors (MLCCs).
This review summarizes the progress of these different classes of ceramic dielectrics for energy storage applications, including their mechanisms and strategies for enhancing the energy storage performance, as well as an outlook on future trends and prospects of lead-free ceramics for advanced pulsed power systems applications.
