Abstract
With the increasing demand for high energy density and reliable dielectric capacitors in the field of power electronics, the research and manufacture of ceramic capacitor materials face significant challenges. At present, the traditional design ideas of dielectric ceramic
materials have gradually formalized, and the system is complex and
similar, whether it can design dielectric ceramic materials with high
performance from a new viewpoint and explore the underlying mechanism
remains a great challenge. This paper is based on ceramic capacitors
with high energy storage performance, a series of high-entropy
perovskite oxide ceramics
designed by the concept of "entropy engineering" in the past five years
are reviewed. The relationship between microstructure and macroscopic
energy storage performance of materials is discussed based on the four
effects of high-entropy ceramics. We predict that "entropy engineering"
will be a successful strategy to break through the bottleneck of
dielectric materials with high energy storage performance. This review
guides the custom design of composition-structure-properties in
high-entropy energy storage ceramics.
