Progress and perspectives in dielectric energy storage ceramics

Dielectric ceramic capacitors,with the advantages of high power density,fast chargedischarge capability,excellent fatigue endurance,and good high temperature stability,have been acknowledged to be promising candidates for solid-state pulse power systems.This review investigates the energy storage performances of linear dielectric,relaxor ferroelectric,and antiferroelectric from the viewpoint of chemical modification,macro/microstructural design,and electrical property optimization.Research progress of ceramic bulks and films for Pb-based and/or Pb-free systems is summarized.Finally,we propose the perspectives on the development of energy storage ceramics for pulse power capacitors in the future.
