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 ].
Then we reviewed the advances of lead-free barium titanate-based ceramic as a dielectric material in ceramic capacitors and discussed the progress made in improving energy storage properties via composition modification, various preparation methods, and structure modification.
In the present work, to improve the energy storage performance of barium titanate-based ceramics, ZBS glass samples to be used as additives for 0.9BaTiO 3 -0.1Bi (Mg 2/3 Nb 1/3 )O 3 (referred to as BT-BMN) ceramics were prepared.
Barium titanate (BT) has an ABO 3 perovskite structure, as shown in Fig. 13. In this structure, the larger Barium (Ba) cations occupy the A -sites at the corners of the unit cell, while the smaller Titanium (Ti) cations occupy the B -sites at the center of octahedra formed by Oxygen (O) atoms.
As a result, pure dielectric BT ceramics have an energy storage density of about 0.4 J/cm 3 (Ogihara et al. 2009).
In this study, we successfully developed ternary-doped energy-storage ceramics with outstanding energy-storage capabilities in BNT matrices. We comprehensively examined their crystal structures, microstates, and energy-storage properties. These insights offer new perspectives for research in the field of lead-free barium titanate-based ceramics.
