Relaxol ferroelectric energy storage

Are relaxor ferroelectrics a good energy storage material?

Relaxor ferroelectrics usually possess low remnant polarizations and slim hystereses, which can provide high saturated polarizations and superior energy conversion efficiencies, thus receiving increasing interest as energy storage materials with high discharge energy densities and fast discharge ability.

What is a relaxor ferroelectric (RFE)?

The energy storage capacity of these compounds has seen rapid enhancement to above 7 J/cm 3 3, 12, 13, 14, 15, 16. Benefiting from the nanoscale heterogeneous polar nanoregions (PNRs) structure, relaxor ferroelectrics (RFEs) are considered to be an excellent option for “dual high” dielectric capacitors 6, 8, 17, 18, 19.

Does SRO modulate energy storage performance in high-entropy relaxor ferroelectrics?

The high activity of the PNRs/polar nanoclusters induced by SRO contributes to superior energy storage performances with excellent stability. In summary, this work proposes a chemical short-range order strategy to modulate energy storage performance in high-entropy relaxor ferroelectrics.

Can chemical short-range order modulate energy storage performance in high-entropy relaxor ferroelectrics?

In summary, this work proposes a chemical short-range order strategy to modulate energy storage performance in high-entropy relaxor ferroelectrics. The polarization switching barriers at chemical short-range regions are lower, enabling rapid response to external electric fields and enhancing the overall energy storage performances.

Does high entropy relaxor ferroelectric modulate performance?

Although high entropy relaxor ferroelectric exhibited enormous potential in functional materials, the chemical short-range order, which is a common phenomenon in high entropy alloys to modulate performances, have been paid less attention here.

Does a short-range order strategy improve functional performance in high entropy relaxor ferroelectrics?

The short-range order strategy is expected to enhance the functional performances in other high-entropy relaxor ferroelectrics.
