Preparation of NASICON-Type Nanosized Solid Electrolyte Li(1.4)Al(0.4)Ti(1.6)(PO(4))(3) by Evaporation-Induced Self-Assembly for Lithium-Ion Battery

A simple and practicable evaporation-induced self-assembly (EISA) method is introduced for the first time to prepare nanosized solid electrolyte Li(1.4)Al(0.4)Ti(1.6)(PO(4))(3) (LATP) for all-solid-state lithium-ion batteries. A pure Na(+) super ion conductor (NASICON) phase is confirmed by X-ray di...

Sumario:A simple and practicable evaporation-induced self-assembly (EISA) method is introduced for the first time to prepare nanosized solid electrolyte Li(1.4)Al(0.4)Ti(1.6)(PO(4))(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(−3) S cm(−1) and 3.63 × 10(−4) S cm(−1) are obtained, with an ion-hopping activation energy as low as 0.286 eV.
