abstract = {Lithium indium alloys are commonly used as
counterelectrodes in all-solid-state batteries. However, the
method ofpreparation varies from research groups, including
ball milling, rollpressing, and uniaxial pressing of the two
metals. While the latter is acommon approach used in the
literature, it is not entirely clear howhomogeneous
uniaxially pressed counter electrodes are and whetherthe
differences can be observed electrochemically. In this work,
in thefirst section, two distinct Li sources, one from the
chemical Li−In alloyand the other from the electrochemical
Li−In alloy formed duringcycling, are electrochemically
probed and investigated as a function ofthe temperature,
indium foil thickness, and Li area. In the secondsection,
the kinetics of electrochemically alloyed Li−In
($e-Li_xIn$) areinvestigated using Butler-Volmer kinetics to
extrapolate exchange current densities in combination with
time and temperature-dependent distribution of relaxation
time (DRT) analyses to better understand the alloying and
dealloying process. These findingsunderscore the
considerable influence that counter electrode preparation
has on the kinetics and electrochemical performance of
twoelectrode half-cells.},
