In this work, a series of (1-x)Sr0.7Ba0.3Nb2O6-xSr0.7Bi0.2TiO3 ceramics were formulated by a phase-mixed sintering, the microstructure and energy storage performance were studied. The introduction of SBT induces the formation of equiaxed crystals leading to the denser microstructure, thus improving the dielectric breakdown strength. In addition, the enhancement of relaxor behavior improves the energy storage performance. For 0.94Sr0.7Ba0.3Nb2O6-0.06Sr0.7Bi0.2TiO3, an energy storage density of 0.49J/cm3 and an efficiency of 94.2% were achieved.

Three-dimensional BaTiO3 (3D BT)/polyvinylidene fluoride (PVDF) composite dielectrics were fabricated by inversely introducing PVDF solution into a continuous 3D BT network, which was simply constructed via the sol-gel method using a cleanroom wiper as a template. The effect of the 3D BT microstructure and content on the dielectric and energy storage properties of the composites were explored. The results showed that 3D BT with a well-connected continuous network and moderate grain sizes could be easily obtained by calcining a barium source containing a wiper template at 1100 °C for 3 h. The as-fabricated 3D BT/PVDF composites with 21.1 wt% content of 3D BT (3DBT–2) exhibited the best comprehensive dielectric and energy storage performances. An enhanced dielectric constant of 25.3 at 100 Hz, which was 2.8 times higher than that of pure PVDF and 1.4 times superior to the conventional nano–BT/PVDF 25 wt% system, was achieved in addition with a low dielectric loss of 0.057 and a moderate dielectric breakdown strength of 73.8 kV·mm−1. In addition, the composite of 3DBT–2 exhibited the highest discharge energy density of 1.6 × 10−3 J·cm−3 under 3 kV·mm−1, which was nearly 4.5 times higher than that of neat PVDF.
