Y doping and grain size co-effects on the electrical energy storage performance of (Pb0.87Ba0.1La0.02) (Zr0.65Sn0.3Ti0.05)O3 anti-ferroelectric ceramics

Enhanced energy storage performance in (Pb0.858Ba0.1La0.02Y0.008)(Zr0.65Sn0.3Ti0.05)O3–(Pb0.97La0.02)(Zr0.9Sn0.05Ti0.05)O3 anti-ferroelectric composite ceramics by Spark Plasma Sintering

“…[11,12], with several dopants addition, the tetragonal AFE ceramics can possess relatively higher recoverable energy density of more than 2.7 J/cm 3 with a large Ps higher than 50 lC/cm 2 [12]. However, the E A of the ceramics was always below 80 kV/ cm which was much lower than the dielectric breakdown strength (BDS).…”

Microstructures and energy storage properties of Mn-doped 0.97Bi0.47Na0.47Ba0.06TiO3–0.03K0.5Na0.5NbO3 lead-free antiferroelectric ceramics

“…Compared to the ferroelectric (FE) materials and linear dielectric materials [1,2], anti-ferroelectric (AFE) materials possess higher energy density (W), and they are more suitable for storage capacitors [3][4][5][6]. As reported, the W value of AFE ceramics ranges from 0.4 to 2.57 J/cm 3 [7][8][9], most of them are included Pb, such as PZST, PLZT, PLZ. Due to bioaccumulation and environmental problems of the Pb-based materials, searching for using lead-free materials to replace lead-based materials is significant.…”

Optimization of energy storage density and efficiency in BaxSr1-xTiO3 (x≤0.4) paraelectric ceramics

“…A key component in power electronics used to deliver very large amounts of energy in a very short time is an energy storage device typically represented by a ceramic capacitor, which can be made of dielectrics, ferroelectrics and anti-ferroelectrics [3][4][5][6][7]. In general, the volumetric energy density γ of a ceramic material is determined by [8]:…”
