Self-consolidation mechanism and its application in the preparation of Al-doped cubic Li7La3Zr2O12

For the preparation of high-density ceramic electrolytes, researchers prefer cold or hot isostatic pressing method, which is not cost effective because of the ultra-high pressure and poor productivity. In this paper, we present a novel “self-consolidation” method to prepare dense cubic Al-doped Li7La3Zr2O12 (LLZO) without the assist of pressing. The relative density of LLZO bulk sample is about 93–96%, and the 0.10 mol Al-doped sample with the...
