For the realization of engineering applications of polymer dielectric materials in energy storage film capacitors, the most significant precondition is fabricating dielectric polymer films with fine structures and tunable macroscopic natures on a large scale through utilizing scalable, reliable, and cost-efficient film processing technologies.
In this review, we present a summary of the current status and development of ceramic-based dielectric capacitors for energy storage applications, including solid solution ceramics, glass-ceramics, ceramic films, and ceramic multilayers.
Abstract: Polymer dielectrics-based capacitors are indispensable to the development of increasingly complex, miniaturized and sustainable electronics and electrical systems. However, the current polymer dielectrics are limited by their relatively low discharged energy density, efficiency and poor high-temperature performance.
This review study summarises the important aspects and recent advances in the development of nanostructured dielectric materials including ceramics, polymers and polymer composites for high-temperature capacitor applications.
