High-density solid electrolyte ceramic with NaF interface rivet and preparation method of high-density solid electrolyte ceramic
The invention is suitable for the technical field of sodium ion batteries, and provides a high-density solid electrolyte ceramic with NaF interface rivets and a preparation method thereof.The preparation method comprises the following steps that anhydrous sodium carbonate, zirconium dioxide, silicon dioxide and ammonium dihydrogen phosphate are weighed according to the stoichiometric ratio, ball-milled and dried to obtain a sample, the sample is placed in a crucible, and the crucible is placed in a furnace for sintering; after pre-sintering, carrying out ball milling and drying again to obtain mixed powder A; pressing the mixed powder A into a blank, performing phase sintering, and cooling to obtain a precursor B; grinding the obtained precursor B, mixing with NaF, and grinding to obtain powder C; and pressing the obtained powder C into a blank, carrying out ceramic forming sintering, and cooling to obtain the high-density Na3Zr2Si2PO12 solid electrolyte ceramic of the NaF interface rivet. According to the invention, the sintering temperature and time are reduced, the densification of the Na3Zr2Si2PO12 solid electrolyte is promoted, and the ionic conductivity of the solid electrolyte is improved.
本发明适用于钠离子电池技术领域，提供了一种NaF界面铆钉的高致密度固态电解质陶瓷及其制备方法，包括以下步骤：将无水碳酸钠、二氧化锆、二氧化硅和磷酸二氢铵按计量比称重，球磨后干燥得到样品，将样品置于坩埚内，预烧后再次球磨干燥得到混合粉末A；将混合粉末A压制成胚料，随后进行成相烧结，冷却后得到前驱体B；将所得前驱体B碾碎后与NaF混合，研磨得到粉末C；将所得粉末C压制成胚料，进行成瓷烧结，冷却后得到NaF界面铆钉的高致密度Na3Zr2Si2PO12固态电解质陶瓷。本发明降低了烧结温度和时间，促进了Na3Zr2Si2PO12固态电解质致密化，提高了固态电解质的离子电导率。
