Structure and ion conducting properties of mixed-alkali Na3–xLixInCl6 solid electrolytes†
Abstract
Li substitution and its impact on the structures and ion transport of Na3−xLixInCl6 polymorphs, synthesized via ball-milling and further annealing, were investigated. Despite a solubility limit of x = 0.6, Li incorporation seems to form a connected Li+ network to enhance the ionic conductivity of the resulting materials.
