abstract = {Previous studies have shown that electrolyte additives
based on metals and semimetals (LiBOB, Mg(TFSI)2, Al(TFSI)3)
as well as additives containing trimethylsiloxyl (TMS)
groups as ligands can have positive impact on the cycling
performance of lithium ion battery cells due to solid
electrolyte interphase (SEI) and/or cathode electrolyte
interphase (CEI) film forming properties and/or scavenging
properties towards acidic impurities. In this study, both
active functionalities (metal core and trialkylsiloxy based
ligands) were combined into one using Al, Ti and B as metal
cores combined with TMS ligands (M(TMS)x). All investigated
additives M(TMS)x were able to improve the cycling
performance regarding Coulombic efficiency, energy
efficiency and capacity retention of LiNi1/3Co1/3Mn1/3O2
(NCM111)/Li half-cells and NCM111/graphite full-cells at
high potentials (>4.3 V vs. Li/Li+). The formed CEI was
studied by means of electrochemical impedance spectroscopy,
scanning electron microscopy and X-ray photoelectron
spectroscopy. The obtained results indicate that the
investigated additives are either actively incorporated into
the formed CEI layer (in case of Al, Ti as metal core) or
interacting with decomposition products (in case of B as
metal core) resulting in lower charge-transfer impedance and
hence improved long-term cycling behavior.},
