      abstract     = {Allylboronic acid pinacol ester (ABPE) was investigated as
                      shutdown overcharge additive to increase the intrinsic
                      safety of lithium ion cells during operation at elevated
                      charge cutoff potentials up to 4.5 V vs. Li/Li+. It was
                      demonstrated that the additive had no negative influence on
                      the cycling performance of LiNi1/3Co1/3Mn1/3O2
                      (NMC-111)/graphite full cells operated in a standard
                      operation voltage range between 2.5 V and 4.2 V.
                      Electrochemical impedance spectroscopy was used to study the
                      influence of the electrolyte additive on the impedance
                      before and after overcharge and concomitant cell shutdown.
                      Thereby, an immense increase in the charge transfer
                      resistance after electrode shutdown was observed, thus,
                      hinting to the formation of a lithium ion-insulating layer
                      on the positive electrode surface. To further elucidate the
                      working principle of the shutdown additive, surface
                      investigations by means of scanning electron microscopy and
                      X-ray photoelectron spectroscopy were carried out. The
                      existence of a surface layer consisting mainly of polymeric
                      species was proven. The presented results open up a new
                      family of compounds for overcharge protection},
