摘要：

This work presents SrO-BaO-Nb2O5-B2O3-P2O5-K2O-TiO2 glass-ceramics prepared by controlled crystallization method. The uniformly dense microstructure with fine grains can be achieved by introducing TiO2. The structural changes were confirmed by the results of SEM and TEM. The 0.5 mol% TiO2 added glass heated at 750 degrees C for 2 h demonstrates excellent comprehensive properties of epsilon(r) = 110, BDS = 1408 kV/cm, high energy storage efficiency (eta) of 92% and energy storage density of 9.65 J/cm(3). The as-prepared glass-ceramic exhibits ultrahigh power density (86.21 MW/cm(3)), actual discharge energy density (1.00 J/cm(3)) and excellent temperature stability. These findings qualify this environment-friendly glass-ceramics as one potential candidate for energy storage applications, especially in high power and pulsed power system field.
