      abstract     = {Within the past 5 years, dual-ion batteries and in
                      particular their all-carbon/all-graphite versions, the
                      dual-carbon or dual-graphite batteries, have received rising
                      interest due to the use of carbonaceous active materials for
                      both, the positive and the negative electrode. With regard
                      to the capacity determining reactions at the positive
                      electrode, related to the intercalation of anions, the
                      influence of the carbon/graphite structure has been by far
                      not fully understood.In this work, we present a
                      comprehensive investigation on the structure – property
                      relationship with special focus on the preparation and
                      characterization of carbon materials with different degree
                      of graphitization (DoG) and their electrochemical
                      performance study as active material for the positive
                      electrode in dual-ion batteries. We found that an increasing
                      DoG directly leads to an enhanced specific discharge
                      capacity, while the crystallite height exhibits only a
                      negligible contribution to the capacity for the carbons
                      examined in this work. A further observation is that the
                      staging mechanism is a major step of the overall anion
                      storage mechanism, even for carbons possessing a low DoG.
                      Moreover, an increased DoG leads to a decreased voltage
                      hysteresis between the charge and discharge step and, thus,
                      to an enhanced voltage efficiency during charge/discharge
                      cycling.},
