Rapid Low-Dimensional Li⁺ Ion Hopping Processes in Synthetic Hectorite-Type Li_0.5[Mg_2.5Li_0.5]Si₄O₁₀F₂.

ABSTRACT: Understanding the origins of fast ion transport in solids is important to develop new ionic conductors for batteries and sensors. Nature offers a rich assortment of rather inspiring structures to elucidate these origins. In particular, layer-structured materials are prone to show facile Li⁺ transport along their inner surfaces. Here, synthetic hectorite-type Li_0.5[Mg_2.5Li_0.5]Si₄O₁₀F₂, being a phyllosilicate, served as a model substance to investigate Li⁺ translational ion dynamics by both broadband conductivity spectroscopy and diffusion-induced ⁷Li nuclear magnetic resonance (NMR) spin-lattice relaxation experiments. It turned out that conductivity spectroscopy, electric modulus data, and NM
