Achieving high energy storage performance through tolerance factor design in Bi0.5Na0.5TiO3 based ceramic
The paper explores strategies to enhance the energy storage efficiency (η) of relaxor- ferroelectric (RFE) ceramics by tailoring the structural parameter tolerance factor (t), which indicates the stability of a perovskite. KTaO3 (KT) with a t of 1.054 has been selected to modulate the t value of 0.75Bi0.5Na0.5TiO3-0.25BaTiO3 (BNT-BT, t = 0.9967), and a serials of (1 − x)(BNT-BT)-xKT (x = 0–0.10) RFE ceramics with t from 0.997 to 1.003 have been prepared. Structural analyses show that all the ceramics possess typical perovskite structure, and the average grain size decrease with the addition of KT. The tested dielectric characteristics present that with the increase of t to 1, the diffuse-phase-transition peak is gradually diminished in the dielectric constant vs temperature (εr-T) curves, while the relaxation-dielectric behavior is gradually strengthened, and the temperature stability of the dielectric constant is improved. The breakdown strength is also enlarged with the increase of KT content. As a result, the 0.94(BNT-BT)-0.06KT with t = 1.0004, which is closest to 1, achieving a recoverable energy storage density (Wrec) of 4.9 J/cm3 and η of 91.8% at 336 kV/cm, which are 191.7% and 49.5% higher than the Wrec (1.68 J/cm3) and η (61.4%) of pure 0.75BNT-0.25BT ceramic, respectively. These findings offer a promising approach for enhance the energy storage properties of RFE ceramics.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
