      abstract     = {The practically available specific energy of Li ion
                      batteries (LIB) is highly depending on the used specific
                      charge/discharge current, since the respective
                      overpotentials of each electrode affect the two vital
                      specific energy parameters, specific capacity and voltage.
                      Focusing on the positive composite electrode as the specific
                      energy bottleneck, the overall nature of the overpotential
                      is discussed for the LiNi1/3Co1/3Mn1/3O2 (NCM) active
                      material. It is shown that the characteristic overpotentials
                      during charge (delithiation) and discharge (lithiation) is
                      state of charge (SOC) and depth of discharge (DOD)
                      dependent, respectively. It was demonstrated that the
                      discharge characteristics are intertwined with the previous
                      charge conditions, particularly with the charging time and
                      the specific charge capacity. Increasing both in parallel
                      can even lead to a deterioration of the subsequent specific
                      discharge capacity. Furthermore, Li+ transport pathways
                      within the NCM composite electrode are discussed and their
                      influence on the observed overpotential evaluated. Changes
                      of the overpotential are found to be mainly associated with
                      changes within the NCM crystal structure, which is
                      experimentally supported by the correlation of the SOC
                      dependent overpotential with the XRD determined c-axis
                      lattice parameter. Consequently, the Li+ transport within
                      the active material is mostly responsible for limiting the
                      practically available specific energy.},
