Ionic Conduction and Electric Modulus in Li<sub>2</sub>S–CaS and Ca<i>X</i><sub>2</sub> (<i>X</i> = F, Cl, Br, and I) Nanocomposites

Technology for ion conduction in Li2S nanostructure has attracted considerable interest achieving the intrinsic performance of Li-S batteries and obtaining highly conductive materials. Herein, a quantitative relationship between transport relaxation behavior Li2S–CaS nanocomposite is revealed based on complex conductivity electric modulus formalism. nanocomposites prepared by high-energy ball milling show higher activation energy than pure Li2S. The lower 80Li2S·20CaS (mol%). long-range involves high compared with hopping carriers at localized states 80Li2S·20CaS. Additionally, dual doping Ca halogen reduces improves findings important insight understanding containing nanostructure.
