“…To better evaluate the energy storage properties of BNS 0.245−1.5x 0.5x B 0.325+x T ceramics, we compared W rec and E max of x = 0.06 and 0.08 compositions with some lead-free ceramic bulks reported previously [45][46][47][48][49][50][51][52][53][54][55]. It can be seen from Fig.…”

Lead-free bulk ceramics for advanced pulsed power capacitors show relatively low recoverable energy storage density (Wrec) especially at low electric field condition. To address this challenge, we propose an A-site defect engineering to optimize the electric polarization behavior by disrupting the orderly arrangement of A-site ions, in which $${\rm{B}}{{\rm{a}}_{0.105}}{\rm{N}}{{\rm{a}}_{0.325}}{\rm{S}}{{\rm{r}}_{0.245 - 1.5x}}{_{0.5x}}{\rm{B}}{{\rm{i}}_{0.325 + x}}{\rm{Ti}}{{\rm{O}}_3}$$ Ba 0.105 Na 0.325 Sr 0.245 − 1.5 x □ 0.5 x Bi 0.325 + x TiO 3 ($${\rm{BN}}{{\rm{S}}_{0.245 - 1.5x}}{_{0.5x}}{{\rm{B}}_{0.325 + x}}{\rm{T}}$$ BNS 0.245 − 1.5 x □ 0.5 x B 0.325 + x T , x = 0, 0.02, 0.04, 0.06, and 0.08) lead-free ceramics are selected as the representative. The $${\rm{BN}}{{\rm{S}}_{0.245 - 1.5x}}{_{0.5x}}{{\rm{B}}_{0.325 + x}}{\rm{T}}$$ BNS 0.245 − 1.5 x □ 0.5 x B 0.325 + x T ceramics are prepared by using pressureless solid-state sintering and achieve large Wrec (1.8 J/cm3) at a low electric field (@110 kV/cm) when x = 0.06. The value of 1.8 J/cm3 is super high as compared to all other Wrec in lead-free bulk ceramics under a relatively low electric field (< 160 kV/cm). Furthermore, a high dielectric constant of 2930 within 15% fluctuation in a wide temperature range of 40–350 °C is also obtained in $${\rm{BN}}{{\rm{S}}_{0.245 - 1.5x}}{_{0.5x}}{{\rm{B}}_{0.325 + x}}{\rm{T}}$$ BNS 0.245 − 1.5 x □ 0.5 x B 0.325 + x T (x = 0.06) ceramics. The excellent performances can be attributed to the A-site defect engineering, which can reduce remnant polarization (Pr) and improve the thermal evolution of polar nanoregions (PNRs). This work confirms that the $${\rm{BN}}{{\rm{S}}_{0.245 - 1.5x}}{_{0.5x}}{{\rm{B}}_{0.325 + x}}{\rm{T}}$$ BNS 0.245 − 1.5 x □ 0.5 x B 0.325 + x T (x = 0.06) ceramics are desirable for advanced pulsed power capacitors, and will push the development of a series of Bi0.5Na0.5TiO3 (BNT)-based ceramics with high Wrec and high-temperature stability.

“…High E b ∼ 466 kV cm –1 is observed, favorable for high W e , which along with the slim P–E loops, is expected to give rise to high energy storage density. The studies have been shown that high η is demanded of multilayers in energy storage applications as waste heat causes potential dissipation problems in the charge–discharge progress. − Figure c shows the W e and η of 0.90BT–0.10BLT multilayers at various electric fields. The W and W e of 0.90BT–0.10BLT multilayers increased from 0.59 and 0.63 to 4.05 and 4.24 J cm –3 , respectively, with the E enhanced from 120 to 466 kV cm –1 .…”

BaTiO3-based materials show great promise for energy storage capacitor but their low breakdown strength and high remnant polarization currently result in relatively low energy density. Here, we report a novel (1-x)BaTiO3-xBi(Li0.5Ta0.5)O3 (0.06 ≤ x ≤ 0.12, BT-xBLT) leadfree ceramic with electric field (E) ~ 280 kV cm-1 , discharge energy density (We) ~ 2.2 J cm-3 , charge-discharge efficiency () >89% that is thermally stable up to 160 °C and with a fast discharge time (≤ 0.5 s). Multilayers of compositions with x = 0.1 also exhibited high We = 4.05 J cm-3 and = 95.5%, demonstrating their potential for energy storage.

“…In the dielectric field, neodymium (Nd) acts as an effective dopant to be widely investigated in singly [1,2,3,4,5] and doubly doped BaTiO 3 (ABO 3 ) ceramics [6,7,8]. In most cases, Nd 3+ substitutes dominate onto Ba sites [1,2,3,4,7]. In the particular case of Ba/Ti = 1 and long-term sintering at 1400 °C for 2–3 days, a self-compensated amphoteric behavior of Nd 3+ in BaTiO 3 was proposed by Hirose et al [5].…”

The (Ba0.96Nd0.04)Ti0.99O3 (BN4T) and (Ba0.96Nd0.04)(Ti0.94Ce0.05)O3 (BN4TC5) ceramics were prepared via the mixed oxide route exhibited tetragonal and pseudo-cubic structures, respectively. After they were preserved over a long period of time, a broader electron spin resonance (ESR) signal at g = 2.338 and a narrow ESR signal at g = 2.151 were detected at room temperature (RT) for BN4T and BN4TC5, respectively. They most likely originated from the Nd3+ Kramers ions in BN4T and Nd3+-Ce4+ defect complexes in BN4TC5 ceramics, respectively. The origins of these two ESR signals and the aging-resistant dielectric behavior are further discussed.
