      abstract     = {The required boost in the specific energy of lithium-ion
                      battery (LIB) cells can only be achieved by increasing the
                      cell voltage and/or the specific capacities of the
                      electrodes. In the latter regard, the positive electrode
                      constitutes the specific energy bottleneck. Lithium
                      transition-metal oxides (LiMO2) such as
                      LiNixMnzCo1−x−zO2 (NMC) are regarded as the most
                      suitable positive electrode materials for next-generation
                      high-specific-energy LIBs. In this work, the
                      electrochemically induced structural stability limits as
                      well as the associated reversible specific energies and
                      specific energy efficiencies were assessed by means of
                      constant current charge/discharge experiments for the most
                      popular and promising LiMO2 compositions. The
                      electrochemically induced structural stability of the
                      positive host material was not determined by the applied
                      charge cut-off potential, but rather by the amount of
                      extracted Li+ ions. In this regard, the electrochemically
                      induced structural stability order of selected LiMO2
                      compositions was modified by assessing the structural
                      stability as a function of the Li+-ion extraction ratio.
                      With respect to application, relevant requirements (e.g.,
                      specific energy, specific energy efficiency,
                      temperature-dependent structural stability, kinetics)
                      revealed that NMC532 and NMC622 showed the best compromise
                      among the various LiMO2 compositions, revealing significant
                      insight into the structure–property relationship.},
