      abstract     = {Dual-ion or dual-graphite batteries based on the mechanism
                      of electrochemical anion intercalation into a graphite
                      cathode have become attractive as an alternative storage
                      technology in recent years. Due to large volume changes of
                      the graphite particles during electrochemical anion
                      intercalation, an appropriate electrode binder is required
                      to sustain the mechanical integrity of the composite
                      electrode and a stable and highly reversible
                      charge/discharge cycling. Therefore, the expansion and
                      contraction behavior of graphite positive electrodes
                      containing different binders, including Na-carboxymethyl
                      cellulose (CMC), poly(vinylidene)difluoride (PVdF) and a
                      CMC/styrene butadiene rubber (SBR) mixture, during anion
                      intercalation/de-intercalation was investigated by in situ
                      electrochemical dilatometry (ECD). These measurements give
                      insights into reversible and irreversible relative height
                      changes at different cycling conditions and, thus, into the
                      long-term cycling stability of the composite
                      electrodes.Long-term cycling measurements reveal that the
                      maximum and minimum electrode thicknesses of PVdF-based
                      electrodes remain constant during anion
                      intercalation/de-intercalation, while the CMC-containing
                      electrodes exhibit a thickness increase in the first cycles
                      and subsequent decrease after reaching a maximum electrode
                      thickness. This instability can most likely be correlated
                      with the mechanical instability of the electrode due to the
                      high stiffness of the CMC binder compared to PVdF and an
                      active material contact loss during cycling. If CMC is
                      applied as binder mixture in combination with SBR, which
                      shows a high flexibility, the thickness decay can be
                      decreased. Our results give new insights into the
                      optimization potentials of composite electrodes for
                      carbon-based cathodes in dual-ion cells that experience
                      large volume expansion during cycling.},
