摘要: Na super ionic conductor (NASICON)-type LiTi 2 (PO 4) 3 as a promising solid electrolyte has been widely used in all-solid-state lithium batteries. However, it still suffers from a low ionic conductivity. Herein, a hydrothermal-assisted solid-state reaction has been developed to synthesize rhombus-like Li 1.3 Al 0.3 Ti 1.7 (PO 4) 3 (LATP) powder. Rhombus-like intermediate species of aluminum-doped NH 4 TiOPO 4 and Li 3 PO 4 are obtained by hydrothermal process, and subsequently the intermediate species are further preheated at …
