Abstract

Solid electrolyte materials Li1.3Al0.3Ti1.7(PO4)3 (NASICON, R-3c) were synthesized via novel acetate routes A (simple precipitate), A1 (spray-dried precipitate) and B (sol–gel synthesis) and their properties are compared. Spray-dried spherical granules show characteristic features as a result of their particular microstructure. Temperature dependent DC measurements provide an informative basis to discuss two different grain boundary ionic conduction mechanisms in these spray-dried granules.

► LATP materials were synthesized via novel acetate routes. ► Particle morphology can be adjusted via synthesis conditions and processing. ► Spray-drying offers an interesting way to increase total ionic conductivity σtot. ► Two grain boundary ionic conduction mechanisms in spherical granules are discussed.
