abstract = {Losses of Li inventory in lithium-ion batteries lead to
losses in capacity and can be compensated by electrode
prelithiation before cell assembly or before cell formation.
The approach of chemical prelithiation, for example, via Li
arene complex (LAC)-based solutions is technically an
apparently simple and promising approach. Nevertheless, as
shown herein on the example of Si-based anodes and LAC
solutions based on 4,4′-dimethylbiphenyl (4,4′-DMBP),
several practical challenges need to be considered. Given
their reactivity, the LAC solution can not only decompose
itself within a range of a few hours, as seen by
discoloration and confirmed via mass spectrometry, but can
also decompose its solvent and binder of added composite
electrodes. Effective prelithiation requires an excess in
capacity of the LAC solution (relative to anode capacity)
and optimized system characteristic conditions (time,
temperature, etc.) as exemplarily shown by comparing
Si-based nanoparticles with nanowires. It is worth noting
that the prelithiation degree alone does not determine the
boost in cycle life, but relevantly depends on previously
applied prelithiation conditions (e.g., temperature), as
well.},
