1. Introduction Barium titanate-based (BaTiO 3 -based) ceramics have been actively studied over the past few decades as dielectric materials in energy storage applications due to their high power density, fast charge/discharge rate, and high stability [ 1, 2, 3, 4, 5 ].
Barium Titanate ceramics are widely used in capacitor field due to their high dielectric constant and low dielectric loss. However, their low energy storage density limits the application in high energy density energy storage devices [ 8, 9 ].
A ferroelectric-paraelectric transition is evidenced from the variation of the dielectric constant with temperature. Barium titanate is one of the most studied perovskite materials owing to its ability to the substitution in both sites, to its high dielectric constant and to its stability.
Besides, the incorporation of the Ca2+ ion into barium titanate results in a slight decrease in the value of Z’. At high frequency, the values of Z’ merge for all temperatures which indicates the existence of space charge polarization .
