Tb energy storage

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.

Can polarization P improve energy storage performance in TTB ceramics?

The optimized polarization ΔP behavior and increased Eb are responsible for the greatly improved energy storage performance in the TTBs ceramics, hold great potential for energy storage application across a broad temperature range. In this research, a series of BSCNT ceramics were fabricated through a high-temperature solid-state reaction method.

How does entropy affect energy storage performance?

The transition from low entropy to high entropy is evident in the enhancement of energy storage performance, increasing from 4.3 J cm −3 (BSCNT0) to 8.9 J cm −3 (BSCNT0.30), representing an increase exceeding 100%. Meanwhile the efficiency also improves significantly, rising from 81% to 93%.

What is the binding energy peak of TB-COF?

The B 1s XPS spectrum of TB-COF shows a dominant binding energy peak at 191.8 eV, corresponding to boroxine ring with C-B-O 2 environment (Fig. 3 b). The peak in TB-COF/S negatively shifts to 191.4 eV, a more negative shift to 191.1 eV is observed in TB-COF/PS.

What is TB-COF binding energy kJ mol 1?

The binding energy (Eb, kJ mol −1) is computed to show the binding strength between the sulfur species and TB-COF. A negative binding energy corresponds to a stable system and a favorable interaction.

What is the capacity of TB-COF/S-58?

TB-COF/S-58 delivers an initial specific capacity of 1044 mAh g −1, corresponding to an areal capacity of 2.3 mAh cm −2. The capacity is maintained at 738 mAh g −1 (1.6 mAh cm −2) after 150 cycles (Fig. S10b).
