What is the energy storage performance of tungsten bronze ceramics?

Benefiting from the synergistic effects, at a large Eb of 760 kV cm −1, breakthrough energy storage performance is realized in tungsten bronze ceramics, including a record-high Wrec of ≈10.6 J cm −3, an ultrahigh η of ≈96.2%, and a record-high figure of merit of ≈279.

Can tetragonal tungsten bronze-type materials be used for energy storage?

The authors present an equimolar-ratio element high-entropy strategy for designing high-performance dielectric ceramics and uncover the immense potential of tetragonal tungsten bronze-type materials for advanced energy storage applications.

Can high-entropy strategy improve energy storage performance in tetragonal tungsten bronze-structured dielectric ceramics?

However, the development of dielectric ceramics with both high energy density and efficiency at high temperatures poses a significant challenge. In this study, we employ high-entropy strategy and band gap engineering to enhance the energy storage performance in tetragonal tungsten bronze-structured dielectric ceramics.

What is the energy storage density of tetragonal tungsten bronze-based ferroelectric?

Thus, an ultrahigh energy storage density of 12.2 J cm −3 with an low energy consumption was achieved at an electric field of 950 kV cm −1. This is the highest known energy storage performance in tetragonal tungsten bronze-based ferroelectric. Notably, this ceramic shows remarkable stability over frequency, temperature, and cycling electric fields.

Are tungsten bronze relaxors suitable for dielectric energy storage?

Further charge–discharge analysis indicates that a high power density (89.57 MW/cm 3) and an impressive current density (1194.27 A/cm 2) at 150 kV/cm are achieved simultaneously. All of the results demonstrate that the tungsten bronze relaxors are indeed gratifying lead-free candidate materials for dielectric energy storage applications.

Can lead-free tungsten bronze be used for high density energy-storage capacitors?

Herein, the novel lead-free tungsten bronze Sr (0.53–0.15x) Ba 0.47 Gd 0.1x Nb 2-x Ta x O 6 (SBGNT) compounds were proposed and fabricated for high density energy-storage capacitors. Compared to pristine SBN ceramics, the relaxor characteristics were regulated effectively by controlling the concentrations of Gd-Ta-co-doping.
