Solid-state battery electrolyte sintering process
The invention provides a solid-state battery electrolyte sintering process, and relates to the technical field of solid-state battery electrolyte sintering, and the solid-state battery electrolyte sintering process comprises the four steps of electrolyte raw material pretreatment, electrolyte raw material molding, electrolyte preformed blank sintering and post-treatment. In the sintering process of the electrolyte preformed blank, the modes of primary sintering, middle-section rapid heating and rear-section calcining are performed, the rapid temperature rising characteristic of microwave sintering is utilized, and meanwhile, the stability and controllability of traditional sintering are kept; the conditions that the temperature is difficult to control when a microwave heating synthesis method is independently adopted and hot spots and thermal runaway are caused by too fast heating are avoided, meanwhile, the effect of improving the sintering efficiency of the solid electrolyte is achieved, and in addition, before sintering, through cooperation of a planetary stirrer and a ball mill and introduction of ethyl alcohol as a dispersing agent, the sintering efficiency of the solid electrolyte is improved. The precursor raw material of the solid-state battery electrolyte is pretreated, and the pretreatment effect is good.
本发明提出一种固态电池电解质烧结工艺，涉及固态电池电解质烧结技术领域，包括电解质原料的预处理、电解质原料的成型、电解质预制坯烧结以及后处理四个步骤，本发明通过将传统高温烧结方式与微波烧结方式相结合，在电解质预制坯烧结的过程中，经历初步烧结、中段快速加热以及后段煅烧的方式，利用微波烧结的快速升温特性，同时保持传统烧结的稳定性和可控性，避免出现单独采用微波加热合成法时的温度难以控制以及加热过快会导致热斑及热失控的情况，同时还具有提高固态电解质烧结效率的效果，此外，在烧结前，通过行星式搅拌机和球磨机的配合，并引入乙醇作为分散剂，对固态电池电解质的前驱体原料进行预处理，预处理效果好。
