Abstract

Dielectric capacitors utilizing ferroelectric compounds have attracted significant research interest due to their high-power density and rapid charge/discharge capabilities. One such promising ferroelectric material is Na_0.5Bi_0.5TiO₃ (NBT), but its typical ferroelectric behavior, characterized by large hysteresis loops, leads to significant energy loss and limits its storage efficiency. In this study, a modified NBT-based compound, Na_0.455Bi_0.375Ca_0.17Ti_0.92Nb_0.08O₃ (NBCTN), was successfully synthesized via the hydrothermal method, which offers lower reaction temperatures and shorter processing times. A pseudocubic structure with the P4mm space group was confirmed by XRD analysis. Dielectric measurements revealed a broad peak at 0 °C with minimal frequency dependence, confirming diffuse ferroelectric phase transition behavior (DPT) contributing to enhanced energy storage characteristics. Room temperature ferroelectric hysteresis loops exhibited a maximum polarization (P_m) of 6.04 μC/cm² and a remnant polarization (P_r) of 0.4 μC/cm² under an applied electric field of 80 kV/cm. Additionally, the NBCTN ceramics demonstrated excellent energy storage performance, achieving a recoverable energy density (W_rec) of 218.90 mJ/cm³ and a high energy efficiency (η) of 82.89 %. These results highlight the potential of NBCTN as a promising candidate for next-generation high-energy-density capacitors.

水热法制备多价Ca2+/Nb5+取代na0.5 bi0.5 tio3基铁电陶瓷的结构、电学和储能性能研究

利用铁电化合物的介质电容器因其高功率密度和快速充放电能力而引起了广泛的研究兴趣。Na0.5Bi0.5TiO3 （NBT）是一种很有前途的铁电材料，但其典型的铁电行为，以大的磁滞回线为特征，导致显著的能量损失并限制了其存储效率。本研究成功地通过水热法合成了一种改性NBCTN (na0.455 bi0.375 ca0.17 ti0.92 nb0.080 o3)，该化合物具有较低的反应温度和较短的处理时间。通过XRD分析，证实其为具有P4mm空间基团的伪晶结构。介电测量显示，在0°C时出现宽峰，频率依赖性最小，证实了弥漫性铁电相变行为（DPT）有助于增强储能特性。室温铁电磁滞回线在80kv /cm电场作用下，最大极化（Pm）为6.04 μC/cm2，残余极化（Pr）为0.4 μC/cm2。此外，NBCTN陶瓷表现出优异的储能性能，可回收能量密度（Wrec）达到218.90 mJ/cm3，能量效率（η）高达82.89%。这些结果突出了NBCTN作为下一代高能量密度电容器的潜力。
