Oxide solid electrolyte and preparation process thereof
The invention discloses an oxide solid electrolyte and a preparation process thereof, and belongs to the technical field of preparation of solid electrolytes. According to the technical scheme, the preparation method comprises the following steps: S1, carrying out ball milling on LiOH, La2O3, ZrO2 and Nb2O5, and drying after ball milling to obtain white powder; s2, grinding the white powder obtained in the step S1, and performing sectional pre-calcination to obtain electrolyte powder; s3, screening the electrolyte powder obtained in the step S2, dropwise adding a binder, fully mixing, and drying to cure the binder; and after drying, tabletting and calcining to finally obtain the oxide solid electrolyte. The cost is low, the method is simple, and the ionic conductivity of the solid electrolyte is improved.
本发明公开了一种氧化物固态电解质及其制备工艺，属于固态电解质的制备技术领域。其技术方案为：S1将LiOH、La2O3、ZrO2和Nb2O5进行球磨，球磨后进行干燥，得到白色粉末；S2将步骤S1得到的白色粉末研磨后进行分段式预煅烧，得到电解质粉体；S3将步骤S2中得到的电解质粉体进行筛选，滴加粘结剂充分混合后，烘干使粘结剂固化；烘干后进行压片煅烧，最后得到氧化物固态电解质。本发明成本低、方法简单，提高了固态电解质的离子电导率。
