High-energy-storage-density barium lithium titanate ceramic and preparation method thereof
The invention relates to a high-energy-storage-density barium lithium titanate ceramic and a preparation method thereof. The chemical formula of the ceramic is BaTi1-xLixO (3-3x/2), x is greater than or equal to 0 and less than or equal to 0.06, and the preparation method of the ceramic comprises the following steps: preparing a barium source, a titanium source and a lithium source according to a stoichiometric ratio, mixing, ball-milling and pre-sintering the prepared raw materials, then ball-milling again, adding a binder to prepare a green body, and finally sintering. The BTL ceramic prepared by the invention has the energy storage density up to 0.88 J/cm < 3 > and the energy storage efficiency up to 64% under an electric field of 100kV/cm, the breakdown strength is also obviously improved, and the highest electric field can reach 140kV/cm. The invention also has the advantages of simple raw materials and process, low production cost, suitability for mass production, no toxicity, harmlessness, environmental protection and the like.
本发明涉及一种高储能密度钛锂酸钡陶瓷及其制备方法。该陶瓷的化学式为BaTi1‑xLixO(3‑3x/2)，0≤x≤0.06，其制备方法如下：按照化学计量比准备钡源、钛源、锂源，将准备好的原料混合球磨进行预烧，接着再次球磨后加入粘结剂制成坯体，最后烧结即可。本发明制得的BTL陶瓷在100kV/cm电场下的储能密度高达0.88J/cm3，储能效率高达64％，击穿强度也明显提升，最高电场可达140kV/cm。本发明还具有原料及工艺简单、生产成本低、适合量产、无毒无害、环保等诸多优点。
