Sr0.7Bi0.2TiO3 (SBT), a kind of lead-free relaxor ferroelectric, is attracting more and more attention for pulse energy storage applications due to the low remnant polarization and high energy storage efficiency (h). However, relatively low dielectric breakdown strength (DBS) limited the recoverable energy storage density (Wrec).
The dielectric loss is undesirable for both energy storage and dielectric applications. The following several aspects should be considered in preparation of low loss polymer composites: (1) combining a low loss polymer matrix with low loss ceramics particles; (2) reducing the introduction of impurities as much as possible, especially ions
The demand for high-temperature dielectric materials arises from numerous emerging applications such as electric vehicles, wind generators, solar converters, aerospace power conditioning, and downhole oil and gas explorations, in which the power systems and electronic devices have to operate at elevated temperatures.
However, the relatively low energy storage density of the dielectric capacitors generally leads to their big sizes, which is difficult to meet the miniaturization requirements of future devices. Polymer-ceramic nanocomposites can combine high permittivity of the ceramic fillers and the excellent breakdown strength of the polymer matrix, thus
