Preparation method of sulfide solid electrolyte
The invention relates to a preparation method of a sulfide solid electrolyte, which comprises the following steps: placing a plurality of raw materials in a closed container, adding a proper amount of ball-milling beads and an organic solvent, keeping the container at a certain rotating speed for a certain time under the condition of inert air, and then carrying out reduced pressure distillation to generate a sulfide solid electrolyte precursor; sintering at a proper temperature to synthesize the sulfide solid electrolyte precursor into the sulfide solid electrolyte. The preparation method disclosed by the invention is simple to operate and easy for industrial production, meanwhile, the ball milling efficiency and the productivity are improved by using the organic solvent, and on the other hand, due to the action of the solvent, the sulfide solid electrolyte can obtain nano-particles with controllable morphology and has relatively high ionic conductivity; therefore, the preparation method has the advantages of being simple in preparation process, high in productivity, high in conductivity and good in performance.
本发明涉及一种硫化物固体电解质的制备方法，本发明是将多种原料放置于密闭容器中，加入适量的球磨珠和有机溶剂，在惰性空气的条件下，使容器处于一定转速和时间后，然后减压蒸馏生成硫化物固体电解质前驱体，然后经过合适的温度烧结后，使硫化物固体电解质前驱体合成为硫化物固体电解质；本发明的制备方法操作简单，易于工业化生产，同时通过有机溶剂的使用，提高球磨效率和产能，另一方面，由于使用溶剂的作用，硫化物固体电解质获得形貌可控的纳米颗粒，具备较高的离子电导率；因此，本发明具有制备过程简单、产能高、提高电导率、性能好的优点。
