Abstract

We report high breakdown strength and excellent energy storage performance of SrTiO3 based ceramics by synergy manipulation.

Bifunctional europium doped SrTiO3 ceramics with energy storage and photoluminescence

“…and 0.83 μm for x = 0, 0.1%, 0.2%, 0.3%, and 0.4%. All samples have a small grain size that beneficial to increase the grain boundary layer width, reduce the mean electric field for the grain boundary layer, and ultimately improve dielectric strength [16]. Furthermore, it is confirmed that all the Sr 1-3x/2 Eu x TiO 3 ceramic elements were uniformly distributed by the element mapping analysis of Fig.…”

“…Finally, a high E b of 440 kV/cm was obtained [15]. [16]. In particular, Dy-doped SrTiO 3 obtains a high recoverable energy density of 4.00 J/cm 3 and an extremely high breakdown strength of 510 kV/cm through oxygen treatment and increasing the resistance of crystal grains and grain boundaries [17].…”

Bifunctional Europium Doped SrTiO3 Ceramics with Energy Storage and Photoluminescence

“…1(a), the average grain sizes of Sr 1-3x/2 EuxTiO 3 ceramics are respectively about 0.85 μm, 1.05 μm, 0.82 μm, 1.08 μm and 0.83 μm for x = 0, 0.1%, 0.2%, 0.3%, and 0.4%. All samples have a small grain size that beneficial to increase the grain boundary layer width, reduce the mean electric field for the grain boundary layer, and ultimately improve dielectric strength[16]. Furthermore, it is confirmed that all the Sr 1-3x/2 Eu x TiO 3 ceramic elements were uniformly distributed by the element mapping analysis of Fig.1 (b).…”

“…Zhu et al It is found that adding an appropriate amount of Bi 3+ can enhance the polarity, reduce the sintering temperature and reduce the grain size, thereby obtaining a higher E b [14]. Pu [16]. In particular, Dy-doped SrTiO 3 obtains a high recoverable energy density of 4.00 J/cm 3 and an extremely high breakdown strength of 510 kV/cm through oxygen treatment and increasing the resistance of crystal grains and grain boundaries [17].…”

Superior energy storage properties in NaNbO3-based ceramics via synergistically optimizing domain and band structures

“…5(f), the comprehensive properties of the NBNT10 ceramics are superior to those of most other lead-free ceramics. 20,22,23,30,40,45–86 Fig. S4† shows the calculated ESP parameters of the NBNT10 ceramics with the growing electric field.…”
