abstract = {Solid-state batteries are an emerging battery technology
rivaling lithium-ion batteries, but before commercialization
can occur, new classes of solid-state electrolytes (SSEs)
must be investigated to better understand the fundamental
properties of these materials and to extend the capabilities
of fast charging and cycle life. In this work, we
investigate glass-ceramic lithium thioborate (LBS) SSEs with
the stoichiometry of $Li_{10}B_{10}S_{20}$ and utilize a
rapid synthesis that enables lithium iodide (LiI)
modification in $Li_{10}B_{10}S_{20}$. We study the
structures of four materials with varying amounts of LiI
using X-ray diffraction, pair distribution function, and
solid-state NMR and find that LiI breaks down the
$B_{10}S_{20}$ supertetrahedra that make up the unit cell of
$Li_{10}B_{10}S_{20}$. More LiI increases ionic conductivity
by increasing the unit cell volume and the fraction of the
glassy phase in the electrolyte. LiI-modified
$Li_{10}B_{10}S_{20}$ as an anode-facing SSE enables
all-solid-state batteries to cycle well with theoretical
capacities up 6.37 $mAh$ $cm^{-2}$ at 0.1C, validating the
relevance of LBS SSEs as separators for solid-state
batteries.},
