AgNbO3-based Pb-free antiferroelectric (AFE) ceramics have attracted increasing interest owing to their excellent potential in energy storage applications. Herein, a high recoverable energy storage density (W rec) of 7.62 J/cm3 is realized in La-doped AgNbO3 ceramics prepared via tape casting. The high W rec is attributed to high breakdown strength E b of 380 kV/cm induced by dense microstructure as well as fine grain size and enhanced AFE stability stemming from M2 phase and reduced tolerance factor t. The high W rec exceeding 6 J/cm3 was maintained in a wide temperature range of 20–150 °C and exhibited frequency stability with less than 8% variation in a range of 1–200 Hz. The discharge energy density W d exhibited temperature stability at 30–110 °C with less than 9% variation. Our research provides a good method for producing AgNbO3-based ceramics having high energy storage performances.

Dielectric capacitors, serving as the indispensable components in advanced high-power energy storage devices, have attracted ever-increasing attention with the rapid development of science and technology. Among various dielectric capacitors, ceramic capacitors with perovskite structures show unique advantages in actual application, e.g., excellent adaptability in high-temperature environments. And the optimization of their energy storage performance has become a hot research topic recently. This review presents the basic principles of energy storage in dielectric ceramics and introduces multi-scale synergic optimization strategies according to the key factors for superior energy storage performance. By summarizing the common points in numerous works, several universal modification strategies are reviewed, and future research on fatigue fracture of ceramic capacitors under multi-field including but not limited to force, electric, and thermal coupling conditions is also anticipated.

“…Typical examples include AN + 0.1 wt% MnO 2 26 and AN + 0.1 wt% WO 3 27 systems, where the U rec reaches 2.5 and 3.3 J cm −3 , respectively. Another is ion substitutions, e.g., replacement of Ag + by La 3+ 28 , Sm 3+ 29 , Ba 2+ 30 , Lu 3+ 31 , Gd 3+ 32 , etc., and/or Nb 5+ by Ta 5+ 33 . The U rec can be effectively increased to 3.2 J cm −3 in Ag 1–3 x La x NbO 3 system at x = 0.02 28 , 4.5 J cm −3 in the Ag 1−3 x Sm x NbO 3 system at x = 0.02 29 , 2.3 J cm −3 in Ag 1–2 x Ba x NbO 3 system at x = 0.02 30 , and 4.2 J cm −3 in Ag(Nb 1– x Ta x )O 3 system at x = 0.15 33 , and so on.…”

Heterovalent-doping-enabled atom-displacement fluctuation leads to ultrahigh energy-storage density in AgNbO3-based multilayer capacitors

Dielectric capacitors with high energy storage performance are highly desired for next-generation advanced high/pulsed power capacitors that demand miniaturization and integration. However, the poor energy-storage density that results from the low breakdown strength, has been the major challenge for practical applications of dielectric capacitors. Herein, we propose a heterovalent-doping-enabled atom-displacement fluctuation strategy for the design of low-atom-displacements regions in the antiferroelectric matrix to achieve the increase in breakdown strength and enhancement of the energy-storage density for AgNbO3-based multilayer capacitors. An ultrahigh breakdown strength ~1450 kV·cm−1 is realized in the Sm0.05Ag0.85Nb0.7Ta0.3O3 multilayer capacitors, especially with an ultrahigh Urec ~14 J·cm−3, excellent η ~ 85% and PD,max ~ 102.84 MW·cm−3, manifesting a breakthrough in the comprehensive energy storage performance for lead-free antiferroelectric capacitors. This work offers a good paradigm for improving the energy storage properties of antiferroelectric multilayer capacitors to meet the demanding requirements of advanced energy storage applications.
