How do antiferroelectric materials store energy

Can antiferroelectrics be used for energy storage and conversion applications?

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.

Should energy storage materials be used in antiferroelectric ceramics?

It should also stimulate the development of novel antiferroelectric ceramics with high energy storage performance. The authors have declared no conflict of interest. Abstract Energy storage materials and their applications have long been areas of intense research interest for both the academic and industry communities.

How does affect the energy storage properties of antiferroelectric materials?

It is thus found that the EAFE- kV/mm to 10.57 kV/mm by varying the Sn content from 0.31 to 0.35 at a fixed Zr content of 0.58. As a result, Wre is significantly enhanced from 0.28 J/cm3 to 2.35 J/cm3 while η simultaneously increases from 31.5% to 86.1%. role in enhancing the energy storage properties of antiferroelectric materials.

What is antiferroelectric material?

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 .

Why do dielectric capacitors use antiferroelectric materials?

Dielectric capacitors using antiferroelectric materials are capable of displaying higher energy densities as well as higher power/charge release densities by comparison with their ferroelectric and linear dielectric counterparts and therefore have greater potential for practical energy storage applications.

What is antiferroelectricity?

A modern definition of antiferroelectricity is not totally unambiguous, but usually one expects at least two attributes in an AFE material.
