abstract = {Pre-lithiation of anode materials can be an effective
method to compensate active lithium loss which mainly occurs
in the first few cycles of a lithium ion battery (LIB), due
to electrolyte decomposition and solid electrolyte
interphase (SEI) formation at the surface of the anode.
There are many different pre-lithiation methods, whereas
pre-lithiation using metallic lithium constitutes the most
convenient and widely utilized lab procedure in literature.
In this work, for the first time, solid state nuclear
magnetic resonance spectroscopy (NMR) is applied to monitor
the reaction kinetics of the pre-lithiation process of
graphite with lithium. Based on static 7Li NMR, we can
directly observe both the dissolution of lithium metal and
parallel formation of LiCx species in the obtained NMR
spectra with time. It is also shown that the degree of
pre-lithiation as well as distribution of lithium metal on
the electrode surface have a strong impact on the reaction
kinetics of the pre-lithiation process and on the remaining
amount of lithium metal. Overall, our findings are highly
important for further optimization of pre-lithiation methods
for LIB anode materials, both in terms of optimized
pre-lithiation time and appropriate amounts of lithium
metal.},
