Sintering method of compact solid electrolyte LATP
The invention discloses a sintering method of a compact solid electrolyte LATP, and the method specifically comprises the following steps: taking 10 g of LATP powder with the purity of more than 99%, and carrying out ball milling for 12 hours by a planetary ball mill at the rotating speed of 300 rpm/min; taking out 0.2 g of LATP powder, putting the LATP powder into a circular mold, and pressing the LATP powder into a uniform wafer with certain strength under the uniaxial pressure of 300MPa; taking out the wafer, putting the wafer between two graphite felts with the size of 80 * 30 * 3mm, introducing a certain current and voltage to the two ends of the graphite felts, ensuring a certain sintering time, and then performing cooling to room temperature to obtain the required compact ceramic sample with the argon flow of 50-250ml/min. The method is easy to operate and low in equipment cost requirement, the LATP ceramic chip can be prepared on a large scale, and the prepared LATP ceramic chip has high density, a sample is complete and free of cracks, the surface is smooth and flat, the relative density is high, and the ionic conductivity is high.
本发明公开了一种致密固态电解质LATP的烧结方法，具体为：取10g纯度大于99％的LATP粉末，行星式球磨机球磨12h，转速为300rpm/min；取出0.2gLATP粉末，放入圆形模具，在单轴压力300MPa下压制成均匀且具有一定强度的圆片；取出圆片，放入两块大小为80*30*3mm的石墨毡中间，在石墨毡两端通入一定电流电压，保证一定烧结时间然后冷却至室温得到所需致密陶瓷样品，氩气流量为50～250ml/min。本发明方法操作简单，对设备成本要求低，并且可以大规模制备LATP陶瓷片，制备的LATP陶瓷片具有较高的致密度，样品完整无裂纹，表面光滑平整，相对密度高，离子电导率高。
