6 FAQs about [Half field energy storage]

Is a high energy-storage coefficient a challenge in dielectric energy storage research?

Achieving superior recoverable energy density (Wrec) and energy efficiency (η) with a high energy-storage coefficient (Wrec/E) at low fields remains a significant challenge in dielectric energy storage research.

Can defreezing coexistent glassy ferroelectric States improve energy storage performance?

NEXT Cite this: ACS Appl. Mater. Interfaces 2024, XXXX, XXX, XXX-XXX In this work, we found that the defreezing coexistent glassy ferroelectric states hold significant potential for achieving superior energy storage performance, especially under low fields, by using phase field simulations and experimental approaches.

How do we achieve high energy storage properties?

The high energy storage properties were achieved using a synergistic strategy involving large polarization, a giant built-in potential/imprint (five times higher than the coercive field), and AFE like behavior.

What is the energy-storage density of pl/20 nm PN heterostructure?

A large recoverable energy-storage density of 43.5 J/cm 3 and a high energy-storage efficiency of 84.1%, were obtained in the 180 nm thick PL/20 nm PN heterostructure under moderate electric field of 2450 kV/cm (i.e., 49 V).

What is high energy storage at low voltages?

High energy storage at low voltages due to synergetic effects of the polarization, imprint, and AFE behavior. Ultra- high U E = U Rec /E=17 J.MV/cm 2 and U F =U Rec / (1-η) =47 J/cm 3 at E= 400kV/cm (i.e., 20V).

Can UREC and improve energy storage performance at low or moderate electric fields?

Despite these efforts to enhance the URec and η at high electric field, few studies have been performed to improve the energy storage performance at low or moderate electric fields, which is of high importance for the devices operating at low voltages, particularly in the case of thicker films.
