Glass-ceramic dielectric materials with high energy density and ultra-fast discharge speed for high power energy storage applications

摘要

Ferroelectric glass-ceramic materials have been widely used as dielectric materials for energy storage capacitors because of their ultrafast discharge speed, excellent high temperature stability, stable frequency, and environmental friendliness. 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. 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. This paper summarizes the research progress of glass-ceramics used in energy storage as well as introduces the concept of energy storage density, analyzes influencing factors, and discusses research direction and development prospects of ferroelectric glass-ceramic materials.
