A review on the development of lead-free ferroelectric energy-storage ceramics and multilayer capacitors. Haibo Zhang * a, Tian Wei a, Qi Zhang * b, Weigang Ma a, Pengyuan Fan a,
The electrostriction of the ceramics under a strong field was greatly reduced, a breakdown strength of 1000 kV cm −1 was obtained, and the energy-storage density was increased to 21.5 J cm −3. In the above, some performance improvement methods for Bi-based energy-storage ceramics have been proposed.
BF-based ceramic materials are considered as potential lead-free energy storage materials due to their theoretical high saturation polarization intensity and high Curie temperature [25, 26]. However, the volatilization temperature of Bi 2 O 3 is low (∼825 °C), and the actual sintering temperature is often much higher than this temperature.
Lead-free ceramics with prominent energy storage properties are identified as the most potential materials accessed in the dielectric capacitors. Nevertheless, high recoverable energy storage density ( W rec ), large energy storage efficiency ( η ) and preferable temperature stability can hardly be met simultaneously.
