摘要
Due to their poor frequency stability and high dielectric loss compared to common energy storage ceramics, bismuth strontium titanate ceramics are rarely employed for energy storage. This paper systematically researches the energy storage characteristics of Sr(1-1.5x)BixTiO3 ceramics. The bismuth strontium titanate ceramics were prepared via the traditional solid phase sintering method. The experiment results indicate that, as x = 0.100, Sr(1-1.5x)BixTiO3 ceramics possess fine frequency stability, high dielectric constant, low dielectric loss, high resistivity, high energy storage efficiency and weak DC electric field dependence of dielectric constant. At 217.6 kV/cm electric field, the energy storage density of Sr(1-1.5x)BixTiO3 ceramic (x = 0.100) reaches 1.63 J/cm3. Therefore, it is a potential dielectric material for energy storage.
