The energy storage density of (1-x) BaTiO3 – x Ba(Mg1/3Nb2/3)O3 (x = 0, 0.1, 0.2, 0.3) ceramics was investigated. The microstructure of samples was characterized by scanning electron microscopy (SEM). The energy storage density was calculated from the P-E hysteresis loops measured at room temperature. Experimental results show that the energy storage density of 0.9 BaTiO3 – 0.1 Ba(Mg1/3Nb2/3)O3 ceramics is highest among all compositions. At 15.8kV/mm electric field, the energy storage density of the sample can reach up to 1.07J/cm3, which is about 1.5 times higher than pure BaTiO3. The improvement of the energy density can be due to two factors: one is the improved breakdown strength caused by the optimized microstructure, the other is the decreased remnant polarization. This result indicates that bulk 0.9 BaTiO3 – 0.1 Ba(Mg1/3Nb2/3)O3 ceramic has advantages compared with pure BaTiO3 ceramic for energy storage applications, and with further improvements in microstructure and reduction of sintering temperature, could be a good candidate for energy storage capacitors.

Storage Properties

Single-perovskite lead-free BaTiO3 ferroelectric films were synthesized on Nb:SrTiO3 substrates by pulsed laser deposition. The microstructure, ferroelectric, electric-field breakdown strength, and energy-storage properties of films were investigated. The remnant polarization [Formula: see text] reached the higher values of 34.79 [Formula: see text]C/cm2. The recoverable energy-storage density [Formula: see text] is 12.30 J/cm3. The results also reveal that rapid thermal processing (RTP) enhances the ferroelectric and energy storage properties of the film by comparison with unannealed, and ferroelectric and energy storage properties exhibit a strong voltage dependence.

High Dielectric

High dielectric polymer nanocomposites are promising candidates for energy storage applications. The main criteria of focus are high dielectric breakdown strength, high dielectric constant and low dielectric loss. In this study, we investigate the effect of the addition of TiO2 particles to PVDF matrix on the dielectric constant, breakdown and energy density of the system. The dispersion of the particles is qualified by scanning electron microscopy (SEM). The morphology of the composites is characterized by polarized light microscopy, Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The dielectric properties are measured by a Novocontrol system with an Alpha analyzer. Finally, the breakdown measurements are carried out by a QuadTech hipot tester.
