High energy storage density glass

Are glass-ceramics a good energy storage material?

Glass-ceramics show a great application potential in sustainable development, environmental protection, high temperature, high voltage resistance, and so on. Given the breakdown strength has a great contribution to the energy storage density, alkali-free niobate-based glass-ceramics have emerged as a prominent energy storage material.

What is ultrahigh recoverable energy storage density (W rec)?

Along with the demand for further miniaturization of high and pulsed power devices, it becomes more and more important to realize ultrahigh recoverable energy storage density (W rec) with high energy storage efficiency (η) and ultrahigh discharge energy storage density (W d) accompanied by high power density (P d) in dielectrics.

What is a high power density electronic device?

Electrical equipment and electronic devices with high power density and integration have been developed in recent years. Glass–ceramic materials with high energy storage density, fast charge–discharge capability, and stable high-temperature performance play an important role in obtaining lightweight and miniature electronic components.

What is high-performance ferroelectric glass–ceramics?

High-performance ferroelectric glass–ceramics have attracted much research attention. Ferroelectric glass–ceramics with high energy storage density have been developed, although their application is limited. The basic mechanism of ferroelectric glass–ceramics requires investigation to improve their performance and meet future energy needs.

What are the dielectric properties of glass-ceramics at room temperature?

Table 1. The dielectric properties of samples at room temperature. W = 1 2 ε 0 ε r E 2 (3) where ε 0 is the dielectric constant of vacuum, ε r is the dielectric constant of glass-ceramics, E is BDS. The maximum W reaches 27.47 J· cm −3 of G840. Thus, this material is an excellent candidate for future high voltage energy storage.

Do high energy densities translate into practical energy-storing devices?

It is obvious that high energy densities do not necessarily translate into practical energy-storing devices owing to the aforementioned high-field-induced issues. Practically it is of great importance to reduce the applied electric field to the energy-storing working body.
