The invention discloses a cubic phase lithium lanthanum zirconium oxide and a preparation method thereof. 1-20 parts of a polymerization agent, 10-150 parts of urea and 400-600 parts of water are mixed and stirred to obtain a first mixture; after the first mixture is heated and kept for a preset time, the precursor is obtained after filtering, washing and drying; The precursor and the lithium salt are mixed, and the mixed powder is obtained after grinding treatment; the mixed powder is sintered to obtain a finished product. The invention has simple process and low production cost, is suitable for large-scale mass production, and can obtain cubic phase lithium lanthanum zirconium oxygen with uniform crystal phase, quasi-micron particle size and good ionic conductivity under the condition of low temperature sintering. |
