Bismuth ferrite-based lead-free energy storage ceramic material and preparation method thereof
The invention discloses a bismuth ferrite-based lead-free energy storage ceramic material and a preparation method thereof, the bismuth ferrite-based lead-free energy storage ceramic material comprises a matrix ceramic with the following chemical general formula: (0.72-x) BiFeO3-0. 28BaTiO3-xLa (Mg1/2Zr1/2) O3, and x is more than or equal to 0 and less than or equal to 0.24. The doping ions La, Mg and Zr are introduced, so that the oxygen vacancy concentration in a bismuth ferrite-barium titanate system is greatly reduced, the problem of large leakage current is solved, the energy storage density and the energy storage efficiency are improved, and the preparation method is simple and controllable in process, high in stability, green and environment-friendly in raw material and low in total cost.
本发明公开了一种铁酸铋基无铅储能陶瓷材料及其制备方法，所述铁酸铋基无铅储能陶瓷材料包括具有如下化学通式的基体陶瓷：(0.72‑x)BiFeO3‑0.28BaTiO3‑xLa(Mg1/2Zr1/2)O3，其中0≤x≤0.24。本发明通过引入掺杂离子La、Mg和Zr，使得铁酸铋‑钛酸钡体系中的氧空位浓度大幅度降低，解决了漏电流大的问题，提升了储能密度和储能效率，并且制备方法工艺简单可控，稳定性高，原材料绿色环保，总体成本低。
