“…We note that for the BNT-8BT ceramics, a slightly pinched loop at RT like ours is uncommon but not unique [19,31,32]. Depolarization temperature of our BNT-8BT ceramic is lower than most reports in the literature.…”

For high power electronics applications, relaxor ferroelectrics are promising materials due to their superior energy storage properties. In this study, we investigate the energy storage properties of novel lead free relaxor ferroelectric ceramics (1−x)(0.92Bi0.5Na0.5TiO3–0.08BaTiO3)–xBi(Li1/3Ti2/3)O3 (abbreviated as BNT–8BT–xBLT). BNT–8BT composition which is close to morphotropic phase boundary was chosen as the base due to its large maximum polarization (P m) and higher ratio of weakly polar tetragonal phase which is expected to facilitate ergodic relaxor behavior and improve energy storage density. The substitution of BLT to the BNT–8BT strongly disrupts the correlations between the polar nanoregions and the transition from nonergodic to ergodic relaxor state occurs already at x = 0.02 BLT at room temperature. Largest energy density (W rec) at 61 kV cm−1 was obtained for x = 0.02 sample (0.656 J cm−3), followed by x = 0.03 (W rec = 0.614 J cm−3) and x = 0.05 (W rec= 0.559 J cm−3). The x = 0.02 sample keeps its energy storage density at high temperatures (i.e. W rec= 0.88 J cm−3, η = 97%, E m= 65 kV cm−1 at 125 °C), while larger electric field (up to 89 kV cm−1) could be applied to the x = 0.05 sample with the smallest grain size and energy density of 1.03 J cm−3 was reached at room temperature. Energy storage density values of BLT substituted materials normalized per unit applied electric field are promising among BNT-based materials.

“…The remnant polarization (Pr) and the coercive electric field (Ec) obtained from the P(E) hysteresis loops are 53.5 µC/cm 2 and 2.5 kV/mm, respectively. The Pr value is slightly higher than reported values, Ec≈30-40 µC.cm -2 [48][49][50], while Ec value have the same order of magnitude Pr≈3 kV.mm -1 [48,49]. Thus, these measured values are characteristics of a wellprepared powder and a well-densified ceramic.…”
