A review: (Bi,Na)TiO3 (BNT)-based energy storage ceramics
The Wrec of BNT-Gd ceramics is only 0.45 J/cm 3 at 25 °C and ulteriorly increases to 0.85 J/cm 3 at 140 °C. Similar to Gd 3+, due to the enhancement of relaxor properties and elongated P-E loop, the ceramic with Ho 3+ substituting Bi 3+ harvests a Wrec (0.68 J/cm 3) but poor η (23.2%) at 114 kV/cm [ 80 ].
