      abstract     = {This study elucidates the presence of a cathode electrolyte
                      interphase (CEI) at graphite positive electrodes (PEs) and
                      assesses its impact on the performance of dual-ion
                      batteries, being promising candidates for cost-efficient and
                      sustainable stationary energy storage. Indeed, electrolyte
                      oxidation increases during charge (5 V vs Li|Li+) for
                      decreased C rates, that is longer duration at high
                      state-of-charges (SOC) , but effective protection and
                      evidence for CEI formation is missing as no increase in
                      Coulombic efficiencies is observed, even with
                      literature-known electrolyte additives like vinylene
                      carbonate, fluoroethylene carbonate, or ethylene sulfite in
                      a highly concentrated base electrolyte (4.0 m LiPF6 in
                      dimethyl carbonate) as reference. Via studying charged and
                      pristine PEs by X-ray photoelectron spectroscopy,
                      PF6−-graphite intercalation compounds and cointercalated
                      solvent molecules are identified, while indications for CEI
                      are absent within 1000 charge/discharge cycles.
                      Nevertheless, a high capacity retention of $≈94\%$
                      (referring to 0.1C) is demonstrated. Affirmed by Raman
                      spectroscopy and scanning electron microscopy, the active
                      material remains structurally stable, suggesting capacity
                      fading to be dominated by resistance rise at the PE, likely
                      due to an electronic contact resistance from active material
                      grain boundaries and/or from the interface between electrode
                      particles and the current collector in course of high volume
                      changes; as systematically derived by impedance
                      spectroscopy.},
