abstract = {Research on lithium metal as a high-capacity anode for
future lithium metal batteries (LMBs) is currently at an
all-time high. To date, the different influences of a highly
pure argon glovebox (GB) and an industry-relevant ambient
dry room (DR) atmosphere have received little attention in
the scientific community. In this paper, we report on the
impact of in coin cell atmosphere (ICCA) on the performance
of an LMB as well as its interphase characteristics and
properties in combination with three organic carbonate-based
electrolytes with and without two well-known
interphase-forming additives, namely fluoroethylene
carbonate (FEC) and vinylene carbonate (VC). The results
obtained from this carefully executed systematic study show
a substantial impact of the ICCA on solid electrolyte
interphase (SEI) resistance (RSEI) and lithium
stripping/plating homogeneity. In a transition metal cathode
(NMC811) containing LMBs, a DR ICCA results in an up to
$50\%$ increase in lifetime due to the improved chemical
composition of the cathode electrolyte interphase (CEI).
Furthermore, different impacts on electrode characteristics
and cell performance were observed depending on the utilized
functional additive. Since this study focuses on a largely
overlooked influential factor of LMB performance, it
highlights the importance of comparability and transparency
in published research and the importance of taking
differences between research and industrial environments
into consideration in the aim of establishing and
commercializing LMB cell components.},
