Sodium niobate-based energy storage ceramic material as well as preparation method and application thereof
The invention discloses a sodium niobate-based energy storage ceramic material as well as a preparation method and application thereof, and the general formula of the sodium niobate-based energy storage ceramic material is (1-x) (0.85 NaNbO3-0.15 A < 0.1 > D < 0.85 > EG3)-xAM, a < 0.1 > D < 0.85 > EG3 is a general formula of a linear dielectric solid solution in NaNbO3; aM is a general formula of a relaxation agent capable of improving the relaxation characteristic of the material; wherein A is a Bi element; x is more than 0 and less than or equal to 0.16. Therefore, the obtained NaNbO3-based ceramic can maintain a relatively high polarization characteristic while improving the breakdown field strength, so that the NaNbO3-based ceramic has high energy storage density under the medium field strength.
本发明公开一种铌酸钠基储能陶瓷材料及其制备方法与应用，其中，该铌酸钠基储能陶瓷材料的通式为(1‑x)(0.85NaNbO3‑0.15A0.1D0.85EG3)‑xAM；A0.1D0.85EG3为固溶在NaNbO3中的线性电介质的通式；AM为能够提高所述材料的驰豫特性的弛豫剂的通式；其中，A为Bi元素；x的取值范围为0＜x≤0.16。由此，得到的NaNbO3基陶瓷在提升击穿场强的同时，也能保持较高的极化特性，从而实现在中场强下具有高储能密度。
