Abstract Dielectric capacitors have become a key enabling technology for electronics and electrical systems. Although great strides been made in the development of ferroelectric ceramic thin films capacitors, much less attention has given to preventing polarization fatigue, while improving energy density, ferroelectrics. Here superior capacitive properties outstanding stability are reported over 10 7 charge/discharge cycles wide temperature range −60 200 °C Aurivillius phase Bi 3.25 La 0.75...
To reach the full potential of polymer dielectrics in advanced electronics and electrified transportation, it calls for efficient operation high-energy-density dielectric polymers under high voltages over a wide temperature range. Here, composites consisting boron nitride nanosheet/polyetherimide TiO2 nanorod arrays/polyetherimide layers are reported. The layered composite exhibits much higher constant than current high-temperature composites, while simultaneously retaining low loss at...
Driven by the information industry, advanced electronic devices require dielectric materials which combine both excellent energy storage properties and high temperature stability. These requirements hold most promise for ceramic capacitors. Among these, modulated Bi0.5 Na0.5 TiO3 (BNT)-based ceramics can demonstrate favorable with antiferroelectric-like properties, simultaneously, attaching superior stability resulted from Curie temperature. Inspired above a strategy is proposed to modulate...

Dielectric capacitors with ultrahigh power densities and fast charging/discharging rates are of vital relevance in advanced electronic markets. Nevertheless, a tradeoff always exists between breakdown strength polarization, which two essential elements determining the energy storage density.

Electrostatic capacitors are emerging as a highly promising technology for large-scale energy storage applications. However, it remains significant challenge to improve their densities. Here, an effective strategy of introducing non-isovalent ions into the BiFeO3 -based (BFO) ceramic capability via delaying polarization saturation is demonstrated. Accordingly, ultra-high density up 7.4 J cm-3 and high efficiency ≈ 81% at 680 kV m-1 realized, which one best performances recorded BFO-based...
The development of new generation dielectric materials toward capacitive energy storage has been driven by the rise high-power applications such as electric vehicles, aircraft, and pulsed power systems.
