Summary: | Bismuth strontium titanate ceramics are rarely used for energy storage. In this paper, the energy storage characteristics of bismuth strontium titanate ceramics (1-(x/3))SrTiO 3 -(x/3)(Bi 2 O 3 ·3TiO 2 ) were systematically researched. The traditional solid phase sintering method was employed for preparing bismuth strontium titanate ceramics. The frequency dependence of dielectric constant, the frequency dependence of the dielectric loss, and the DC electric field dependence of dielectric constant were measured. The energy storage density was obtained by integrating the area within the polarization axis and the discharge curve in the polarization-electric field (P-E) curve. Experimental results show that, when x=0.15, (1-(x/3))SrTiO 3 -(x/3)(Bi 2 O 3 ·3TiO 2 ) ceramic has high dielectric constant, fine frequency stability, high resistivity, low dielectric loss and weak DC electric field dependence of dielectric constant. And its energy storage density could achieve 1.63 J/cm 3 at 217.6 kV/cm electric field. Thus, it may possess the potential being used as a kind of energy storage dielectric material. |
