The energy storage mechanism of antiferroelectric capacitor is

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 field-driven transition from antiferroelectric to ferroelectric?

Field-driven transition from antiferroelectric (AFE) to ferroelectric (FE) states has gained extensive attention for microelectronics and energy storage applications. High dielectric-breakdown-strength (DBDS) for a given material is a necessity to attain full capacity of electrical energy storage.

Are antiferroelectric ceramics a good choice for pulse capacitors?

Antiferroelectric ceramics, thanks to their remarkable energy storage density W, superior energy storage efficiency η, and lightning-fast discharging speed, emerge as the quintessential choice for pulse capacitors [, , ].

Are antiferroelectric relaxors effective in energy storage?

Antiferroelectric relaxors (AFR) have attracted increasing attention for their potential to achieve large energy storage density and high efficiency simultaneously. However, the underlying mechanism behind their superior energy storage performance remains unclear.

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.

Is antiferroelectricity a resurgence in energy-efficient applications?

As a close relative of ferroelectricity, antiferroelectricity has received a recent resurgence of interest driven by technological aspirations in energy-efficient applications, such as energy storage capacitors, solid-state cooling devices, explosive energy conversion, and displacement transducers.
