abstract = {Li10GeP2S12 is a phosphosulfide solid electrolyte that
exhibits exceptionally high Li-ion conductivity, reaching a
conductivity above 10–3 S cm–1 at room temperature,
rivaling that of liquid electrolytes. Herein, a method to
produce glassy-ceramic Li10GeP2S12 via a single-step
utilizing high-energy ball milling was developed and
systematically studied. During the high energy milling
process, the precursors experience three different stages,
namely, the ‘Vitrification zone’ where the precursors
undergo homogenization and amorphization, ‘Intermediary
zone’ where Li3PS4 and Li4GeS4 are formed, and the
‘Product stage’ where the desired glassy-ceramic
Li10GeP2S12 is formed after 520 min of milling. At room
temperature, the as-milled sample achieved a high ionic
conductivity of 1.07 × 10–3 S cm–1. It was determined
via quantitative phase analyses (QPA) of transmission X-ray
diffraction results that the as-milled Li10GeP2S12 possessed
a high degree of amorphization (44.4 wt $\%).$ To further
improve the crystallinity and ionic conductivity of the
Li10GeP2S12, heat treatment of the as-milled sample was
carried out. The optimal heat-treated Li10GeP2S12 is almost
fully crystalline and possesses a room temperature ionic
conductivity of 3.27 × 10–3 S cm–1, an over $200\%$
increase compared to the glassy-ceramic Li10GeP2S12. These
findings help provide previously lacking insights into the
controllable preparation of Li10GeP2S12 material.},
