abstract = {Lithium metal batteries are promising next-generation
rechargeable batteries with high energy density. However,
the high reactivity of lithium metal leads to an undesirable
growth of high surface area lithium during electrodeposition
and -dissolution and remains a key challenge that must be
addressed to enable commercialization. Modification of the
Li metal surface to obtain protective coatings is a common
method to overcome these challenges. In this study, the
influence of the thickness of an intermetallic coating on Li
metal is investigated after application by means of thermal
evaporation. In addition, the relevance of pre-treatments in
reducing the native layer thickness and surface roughness by
roll-pressing Li metal prior to coating is demonstrated.
Morphological analyses are performed on cross-sections
prepared under cryogenic conditions to investigate the
origin of high surface area lithium growth and coating
cracks after electrodeposition and -dissolution processes.
The results obtained support the conclusion that the
exclusive combination of roll-pressed Li metal foil followed
by coating reduces overvoltage and improves cycle life at
elevated current densities.},
