Progress and perspectives in dielectric energy storage ceramics

Abstract

Dielectric ceramic capacitors, with the advantages of high power density, fast charge-discharge 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.

Energy Storage Application of All-Organic Polymer Dielectrics: A Review

“…The conventional method employs inorganic fillers, such as ceramic particles, to fill the polymer matrix, resulting in a two-phase composite material composed of inorganic particles and polymer to improve the energy storage characteristics of the polymer-based dielectric [47]. As a result, low breakdown strength and significant dielectric loss are observed [48,49].…”

Enhanced Thermal Stability in Dielectric Properties of NaNbO3–Modified BaTiO3–BiMg1/2Ti1/2O3 Ceramics for X9R-MLCC Applications

“…Among the electronic components, the capacitor is one of the most widely used components for both low temperature, as well as harsh environment applications [1][2][3][4]. The present market of ceramic capacitors is dominated by the multi-layer ceramic capacitor (MLCC), having the advantages of both high volumetric efficiency and small size [5][6][7]. Trillions of pieces are fabricated every year which makes it one of the most widely used components used in electronic circuits [8].…”
