                      (NCMxyz) materials, such as NCM523, are the most promising
                      cathode materials for high‐energy lithium‐ion batteries
                      (LIBs). One major strategy to increase the energy density of
                      LIBs is to expand the cell voltage (>4.3 V). However,

                      graphite full cells typically suffer from drastic capacity
                      fading, often referred to as “rollover” failure. In this
                      study, the underlying degradation mechanisms responsible for
                      failure of
                      NCM523urn:x-wiley:18645631:media:cssc202002113:cssc202002113-math-0003
                      graphite full cells operated at 4.5 V are unraveled by a
                      comprehensive study including the variation of different
                      electrode and cell parameters. It is found that the
                      “rollover” failure after around 50 cycles can be
                      attributed to severe solid electrolyte interphase growth,
                      owing to formation of thick deposits at the graphite anode
                      surface through deposition of transition metals migrating
                      from the cathode to the anode. These deposits induce the
                      formation of Li metal dendrites, which, in the worst cases,
                      result in a “rollover” failure owing to the generation
                      of (micro‐) short circuits. Finally, approaches to
                      overcome this dramatic failure mechanism are presented, for
                      example, by use of single‐crystal NCM523 materials,
                      showing no “rollover” failure even after 200 cycles.
                      The suppression of cross‐talk phenomena in high‐voltage
                      LIB cells is of utmost importance for achieving high cycling
                      stability.},
