Impedance and energy storage properties of NBT-SrTiO3–KNbO3lead-free ceramics
Among the notable features of the lead-free material KNbO3 (KNb) are its exceptional energy storage density (Wrec) and high breakdown electric field strength (Eb). However, the considerable energy loss associated with KNb limits its applicability in energy storage, adversely affecting both Wrec and efficiency (η) under strong electric fields. This study explores an innovative approach to enhance the energy storage capacity of NBT-SrT-xKNb ceramics (x = 0.1–0.4). The incorporation of KNb disrupts the long-range ordered structure and effectively reduces grain size, resulting in the formation of polar nanoregions (PNRs) that help mitigate energy density loss. As the concentration of KNb increases, significant improvements in both Wrec and η are observed. NBT-SrT-xKNb (x = 0.3) exhibits the best performance among all variations, achieving a high energy storage density (Wrec = 3.13 J/cm3), rapid conversion efficiency (η = 85%), and excellent breakdown strength. Under a mild electric field 30 kV/cm, the substitution of KNb results in a significant strain response of approximately 0.24%. Additionally, a longitudinal strain value of 129 pC/N was recorded. These lead-free ceramics present compelling candidates for current energy storage applications as well as next-generation electro 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.
