LGPS ceramic chip and preparation method thereof, and pressing die of LGPS ceramic chip
The invention relates to the technical field of preparation of solid electrolyte, in particular to an LGPS ceramic chip, a preparation method thereof and a pressing die of the LGPS ceramic chip, and the preparation method provided by the invention comprises the following steps: carrying out compression molding on Li10GeP2S12 powder to obtain the Li10GeP2S12 ceramic chip; the pressure for compression molding is 0.5 to 3.0 GPa, and the pressure maintaining time is 3 to 10 minutes. According to the method, Li10GeP2S12 powder is pressed under high pressure (0.5-3.0 GPa), so that the number of air holes at a grain boundary can be reduced, a shortcut with good contact among regional grains can be formed, a grain boundary potential barrier and a migration path can be reduced, the migration rate of ions in a solid phase can be improved, and the ionic conductivity can be improved.
本发明涉及固态电解质的制备技术领域，具体涉及一种LGPS陶瓷片及其制备方法、LGPS陶瓷片的压制模具，本发明提供的制备方法，包括以下步骤：将Li10GeP2S12粉末进行压制成型，得到所述Li10GeP2S12陶瓷片；所述压制成型的压力为0.5～3.0GPa，保压时间为3～10min。本发明采用高压力(0.5～3.0GPa)对Li10GeP2S12粉末进行压制，可以降低晶界处的气孔数目，形成区域晶粒间接触良好的“捷径”，降低晶界势垒和迁移路径，提高离子在固相中的迁移速率，从而提高了离子电导率。
