What is the energy storage potential of tetragonal tungsten bronze structure ceramic?

As an important category of dielectric materials, the energy storage potential of the tetragonal tungsten bronze structure ceramic has been underestimated for a long time due to the lower dielectric constant and low breakdown strength.

Can tungsten oxide based materials save energy?

Authors to whom correspondence should be addressed. Tungsten oxide-based materials have drawn huge attention for their versatile uses to construct various energy storage devices. Particularly, their electrochromic devices and optically-changing devices are intensively studied in terms of energy-saving.

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 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.

Are tungsten oxide-based solar cells multifunctional?

Furthermore, based on close connections in the forms of device structure and working mechanisms between these two main applications, bifunctional devices of tungsten oxide-based materials with energy storage and optical change came into our view, and when solar cells are integrated, multifunctional devices are accessible.

How to improve bifunctional performance of tungsten oxides electrode?

Approaches to enhance bifunctional performances of tungsten oxides electrode are very similar to those that improve electrochromic performance and energy storage performances. They are merely getting porous nanostructure, doping, and integrating tungsten oxide with other materials, especially organic materials (see Table 1, Table 2 and Table 3 ).
