## Description

- description: 'Understanding the structure–property relationships in glasses remains
    challenging owing to their structural complexity, especially in multicomponent
    practical glasses. In this work, neutron diffraction with isotopic substitution
    was employed to investigate lithium coordination environments in halide (chloride
    and/or bromide)-doped borate glasses, which exhibit variations in lithium-ion
    conductivity associated with anion mixing. Lithium-specific neutron pair distribution
    function analysis reveals that the conductivity enhancement in oxide–halide mixed
    glasses originates from the breaking of one short Li–O bond and the formation
    of two longer Li–halogen bonds. The formation of LiO3Cl2 and LiO3Br2 units is
    observed in chloride- and bromide-doped glasses, respectively, whereas a glass
    containing equal amounts of chloride and bromide exhibits LiO3ClBr units in addition
    to LiO3Cl2 and LiO3Br2 units. These results suggest that the coexistence of multiple
    lithium–oxygen–halogen polyhedral units hinders lithium-ion migration, leading
    to reduced ionic conductivity in halide–halide mixed glasses. This work provides
    new insights into the structure–property relationships in lithium-ion conducting
    glasses through lithium-specific structural analysis. '
