Abstract

The Ti_0.995(In_0.5Nb_0.5)_0.005O₂/SrO-B₂O₃-SiO₂ glass-ceramics for dielectric energy storage applications were prepared and investigated. The optimal microstructure of the glass-ceramics has been achieved by adopting Ti_0.995(In_0.5Nb_0.5)_0.005O₂ with colossal dielectric constant as grains and SrO-B₂O₃-SiO₂ glass with high resistivity as grain boundaries. After the introduction of SrO-B₂O₃-SiO₂ glass, it was found that the breakdown strength increased several times higher than that of pristine Ti_0.995(In_0.5Nb_0.5)_0.005O₂ ceramics. Meanwhile, the energy density increased more than four times and energy efficiency is more than one time. An outstanding energy density of 1.55 J/cm₃ and a high energy efficiency of 70% for Ti_0.995(In_0.5Nb_0.5)_0.005O₂ ceramic with 2 wt% SrO-B₂O₃-SiO₂ glass were obtained at an electric field of 328.3 kV/cm, suggesting that this kind of glass-ceramic could be an attractive candidate for energy storage applications.
