The invention belongs to the field of materials, and particularly relates to a ceramic material and a preparation method and application thereof. The general formula of the ceramic material is (1-x) (Ba0.85Ca0.15Zr0.1Ti0.9O3) x (Sr0.7Bi0.2TiO3), wherein x is more than or equal to 0.1 and less than or equal to 0.4. According to the invention, Ba (0.85) Ca0.15Zr0.1Ti0.9O3 is properly modified by Sr0.7Bi0.2TiO3, the obtained ceramic material simultaneously achieves high energy storage density and high energy storage efficiency, the high energy storage efficiency can effectively prevent stored energy from being released in the form of heat, and the service life of the material is prolonged. 本发明属于材料领域，具体涉及一种陶瓷材料及其制备方法和用途。本发明中陶瓷材料的通式为(1-x)(Ba0.85Ca0.15Zr0.1Ti0.9O3)x(Sr0.7Bi0.2TiO3)，其中0.1≤x≤0.4。本发明通过Sr0.7Bi0.2TiO3对Ba0.85Ca0.15Zr0.1Ti0.9O3进行适当改性，获得的陶瓷材料同时达到高储能密度和高储能效率，其中高储能效率能够有效避免存储的能量以热的形式释放，延长材料的使用寿命。
