Herein, we provide perspectives on the development of antiferroelectrics for energy storage and conversion applications, as well as a comprehensive understanding of the structural origin of antiferroelectricity and field-induced phase transitions, followed by design strategies for new lead-free antiferroelectrics.
In this review, the recent progress as regards the energy storage performance of antiferroelectric ceramics, including PbZrO3-based, AgNbO3-based and (Bi,Na)TiO3-based are summarized. The low temperature sintering techniques and the charge-discharge properties of antiferroelectric ceramics are also discussed from a practical point of view.
Antiferroelectric material is another category of dielectric materials which exhibits excellent energy storage characteristics. The dipoles in the antiferroelectric materials are oriented in an antiparallel direction, which is primarily responsible for macroscopic spontaneous polarization .
Continued efforts are being devoted to find materials with high energy density, and antiferroelectrics (AFEs) are promising because of their characteristic polarization–electric field (P – E) double hysteresis loops schematized in Fig. 1a (ref. 4).
Since the brittleness and high electric field induced strain of the antiferroelectric ceramics, there is concern about the reliability of the materials for energy storage application. It is advantageous to develop antiferroelectric polymers for this application. Figure 10.24.
The review will be of benefit for researchers in the area as it offers a quick overview of recent progress in the development of various kinds of antiferroelectric ceramics and their properties. It should also stimulate the development of novel antiferroelectric ceramics with high energy storage performance.

En los materiales que exhiben antiferromagnetismo, los momentos magnéticos de los átomos o moléculas, generalmente relacionados con los espines de los electrones, se alinean en un patrón regular con espines vecinos (en subredes diferentes) que apuntan en direcciones opuestas.Esto es, como el ferromagnetismo y el ferrimagnetismo, una manifestación del magnetismo ordenado.
