Garnet type solid electrolyte and preparation method thereof
The invention belongs to the field of lithium batteries, and provides a garnet type solid electrolyte and a preparation method thereof. The chemical formula of the garnet type solid electrolyte is Li < 7-2x > La < 3 > Zr < 2-x > Mo < x > O < 12 >, x is equal to 0.05-0.2, and the method comprises the following steps: (1) preparing a solution A, dissolving a solution B and a solution C; (2) mixing the solution A, the solution B and the solution C to obtain a mixed solution; (3) heating the mixed solution to obtain a solid product; (4) performing first roasting on the solid product to obtain a precursor; (5) grinding the precursor to obtain precursor powder; (6) performing cold pressing on the precursor powder to obtain a mold pressing precursor; and (7) covering the molded precursor with the precursor powder, and then carrying out second roasting to obtain the garnet type solid electrolyte. The garnet type solid electrolyte is prepared by adopting a sol-gel method, the cost is low, the operation is simple, and the obtained garnet type solid electrolyte is stable in crystal form and relatively high in ionic conductivity.
