Particularly, ceramic-based dielectric materials have received significant attention for energy storage capacitor applications due to their outstanding properties of high power density, fast charge–discharge capabilities, and excellent temperature stability relative to batteries, electrochemical capacitors, and dielectric polymers.
Significant progress has been made toward the development of dielectric ceramic film capacitors with high energy storage performance. The authors declare no conflict of interest.
Even though strenuous efforts have been dedicated to closing the gap of energy storage density between the dielectric capacitors and the electrochemical capacitors/batteries, a single-minded pursuit of high energy density without a near-zero energy loss for ultrahigh energy efficiency as the grantee is in vain.
The energy storage performance of dielectric ceramic materials is closely related to the crystal structure of the material itself. According to the existence of dipoles, energy storage dielectric ceramics are divided into two types: linear dielectrics and nonlinear dielectrics.
Dielectric capacitors have high power density but limited energy storage density, with a more rapid energy transfer than electrochemical capacitors and batteries; this is because they store energy via dielectric polarization in response to the external electrical fields rather than chemical reactions [3, 12, 13, 35].
This approach should be universally applicable to designing high-performance dielectrics for energy storage and other related functionalities. Multilayer ceramic capacitors (MLCCs) have broad applications in electrical and electronic systems owing to their ultrahigh power density (ultrafast charge/discharge rate) and excellent stability (1 – 3).
