Abstract
Ceramics with high-energy storage density are in high demand across various industries. In this regard, lead-free
relaxor ferroelectric ceramics were synthesized using the conventional solid-state reaction method with the
composition (1-x)[0.94Bi Na TiO -0.06BaTiO ]-xSr Biγ Ti Zr O 0.95 , abbreviated as BNBT-xSBTZ. The

incorporation of SBTZ in BNBT ceramics significantly improved their relaxation properties. Specifically, the
0.91BNBT-0.09SBTZ ceramics displayed a breakdown electric field of up to 230 kV/cm, with a recoverable energy
3
storage density (Wr) of 2.68 J/cm and an energy storage efficiency (η) of 74.4%. Additionally, this sample
demonstrated remarkable temperature stability and fatigue resistance, with only an 11% decrease in Wr observed
5
from room temperature to 140 °C and a 13.3% reduction in Wr after 10 electrical cycles. Therefore, the 0.91BNBT-
0.09SBTZ ceramic is a promising dielectric material suitable for energy-storage dielectric capacitors.
Keywords: Energy storage properties, lead-free ceramics, temperature stability, fatigue resistance
