Exploring novel bismuth-based materials for energy storage applications

Abstract

The increasing consumption of compact electronics impels us to design high-performance dielectric energy storage materials. Bi0.5K0.5TiO3-based materials, which have been ignored thus far in energy storage applications, possess an ultrahigh stored energy density (WS = 3.07 J cm−3) and recoverable energy storage density (WR = 2.08 J cm−3), as well as excellent thermal stability (the variation in WR is less than 8% over the range of 25–140 °C) when using a hot-press sintering technique. Moreover, by means of charge–discharge evaluations, the stored energy is released in a very short time (∼0.2 μs), regardless of variations in the temperature. The results presented here strongly indicate that the elaborately designed Bi0.5K0.5TiO3–0.06La(Mg0.5Ti0.5)O3 ceramic is a promising candidate for energy storage applications.
