The demand for dielectric capacitors with higher energy‐storage capability is increasing for power electronic devices due to the rapid development of electronic industry. Existing dielectrics for high‐energy‐storage capacitors and potential new capacitor technologies are reviewed toward realizing these goals. Various dielectric materials with desirable permittivity and dielectric breakdown strength...
SrSnxTi(1−x)O3 (x=0, 0.01, 0.03, 0.05, 0.07) dielectric ceramics were fabricated by the solid state reaction method. Significant refinement of grain size and improved resistivity were observed with the addition of Sn, accounting for effectively enhanced dielectric breakdown strength, beneficial for the energy storage applications. Impedance analysis was employed to calculate the conductivities of...
In this paper, zinc borosilicate glasses (ZnO-B2O3-SiO2) were added to Ba0.3Sr0.7TiO3 (BST) ceramics, to determine the role of glass additives on the dielectric properties and energy storage density of BST. Microstructure, relative density, dielectric properties and the breakdown strength (BDS) were investigated. The dependence of permittivity and BDS on the glass composition were discussed. The results...
