abstract = {Increasing the operation voltage of electrochemical energy
storage devices is a viable measure to realize higher
specific energies and energy densities. A sufficient
oxidative stability of electrolytes is the predominant
requirement for successful high voltage applicability. The
common method to investigate oxidative stability of LIB
electrolytes is related to determination of the
electrochemical stability window (ESW), on e.g. Pt or
LiMn2O4 electrodes. However, the transferability of the
obtained results to practical systems is questionable for
several reasons. In this work, we evaluated the validity of
the potentiodynamic based ESW method by comparing the
obtained data with the results of galvanostatic based
techniques, applied on commercial positive electrodes. We
demonstrated that the oxidative stabilities, determined by
the two techniques, are in good accordance with each other.
However, the investigation of electrolytes being
incompatible to Li metal, renders conventional ESW
measurements useless when metallic Li is used as counter –
and reference electrode in the ESW setup. For this reason,
we introduced an alternative setup based on Li4Ti5O12 full
cells. On the example of a butyronitrile-based electrolyte,
we finally demonstrated that this electrolyte is not only
reductively but also oxidatively less stable than common
LiPF6/organic carbonate based electrolytes.},
