abstract = {In ‘zero-excess’ (often called ‘anode-free’)
lithium metal batteries (ZE-LMBs), three-dimensional (3D)
current collectors (CC) with a high surface area have been
reported to effectively reduce the local current density and
minimize the electronically and/or ionically isolated Li
metal, so-called ‘dead Li’. In most of the published
works on 3D CCs for ZE-LMBs, the discussion has oftentimes
primarily emphasized the relationship between the
functionality of the 3D surface structure and its effect on
enhanced electrochemical performance. Therefore, it is
important to take a deeper look at this relationship by
controlling the surface features and surface chemistry of
CCs. In this work, the direct correlation between the
surface area of CCs and ‘dead Li’ is thoroughly
evaluated. The Li deposition behavior at the entire CC is
also elucidated. A fair comparison is maintained by
precisely controlling surface features and surface chemistry
of the 3D copper CC which is realized by
femtosecond-laser-ablation. ‘Dead Li’ is accurately
quantified by gas chromatography coupled with a barrier
discharge ionization detector. This study shall shed light
on a deeper understanding of the correlation between surface
area and ‘dead Li’ to pave the way for the application
of ZE-LMBs.},
