Garnet type solid electrolyte and preparation method and application thereof
The invention provides a garnet type solid electrolyte and a preparation method and application thereof.The preparation method comprises the following steps that a lithium source, a lanthanum source and a zirconium source are subjected to wet ball-milling mixing according to the formula amount, and a ball-milled material is obtained; and tabletting the ball-milled material to obtain a sheet-shaped object, and then carrying out pressurized heating sintering on the sheet-shaped object to obtain the garnet type solid electrolyte, according to the preparation method, the raw materials can be uniformly mixed, and generation of through holes in the solid electrolyte can be reduced, so that the obtained solid electrolyte has relatively high compactness, ionic conductivity and thermal stability.
本发明提供了一种石榴石型固体电解质及其制备方法与应用，所述制备方法包括如下步骤：按配方量将锂源、镧源和锆源进行湿法球磨混合，得到球磨料；将所述球磨料进行压片，得到片状物，然后将片状物进行加压升温烧结，得到所述石榴石型固体电解质；所述制备方法不仅能够使原料混合均匀，还能减少固体电解质内部通孔的产生，使得到的固体电解质具备较高的致密性、离子电导率以及热稳定性。
