Abstract
eramics with high-energy storage density are in high demand across various industries. In this regard, lead-free relaxor ferroelectric ceramics were synthesized using the conventional solid-state reaction method with the composition (1-x)[0.94Bi0.5Na0.5TiO3-0.06BaTiO3]-xSr0.8Biγ0.1Ti0.8Zr0.2O0.95, abbreviated as BNBT-xSBTZ. The incorporation of SBTZ in BNBT ceramics significantly improved their relaxation properties. Specifically, the 0.91BNBT-0.09SBTZ ceramics displayed a breakdown electric field of up to 230 kV/cm, with a recoverable energy storage density (Wr) of 2.68 J/cm3 and an energy storage efficiency (η) of 74.4%. Additionally, this sample demonstrated remarkable temperature stability and fatigue resistance, with only an 11% decrease in Wr observed from room temperature to 140 °C and a 13.3% reduction in Wr after 105 electrical cycles. Therefore, the 0.91BNBT-0.09SBTZ ceramic is a promising dielectric material suitable for energy-storage dielectric capacitors
期刊介绍：
Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover:
• Novel micro and nanostructures
• Nanomaterials (nanowires, nanodots, 2D materials ) and devices
• Synthetic heterostructures
• Plasmonics
• Micro and nano-defects in materials (semiconductor, metal and insulators)
• Surfaces and interfaces of thin films
In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
