title: Preparation of NASICON-Type Nanosized Solid Electrolyte Li1.4Al0.4Ti1.6(PO4)3by Evaporation-Induced Self-Assembly for Lithium-Ion Battery.
abstract: A simple and practicable evaporation-induced self-assembly (EISA) method is introduced for the first time to prepare nanosized solid electrolyte Li1.4Al0.4Ti1.6(PO4)3(LATP) for all-solid-state lithium-ion batteries. A pure Na+super ion conductor (NASICON) phase is confirmed by X-ray diffraction (XRD) analysis, and its primary particle size is down to 70 nm by optimizing evaporation rate of the solvent. Excellent room temperature bulk and total lithium-ion conductivities of 2.09 × 10-3S cm-1and 3.63 × 10-4S cm-1are obtained, with an ion-hopping activation energy as low as 0.286 eV.
