abstract = {A hybrid cathode concept that targets combining the
specific advantages of Li-ion batteries and dual-ion
batteries is proposed. LiNi0.5Mn1.5O4 (LNMO), (de)inserting
Li+, and graphite, capable to (de)intercalate PF6− present
in the electrolyte, are combined in one cathode, aiming for
synergy effects due to the presence of two electrochemically
active species to overcome rate limitations caused by
electrolyte depletion. Hybrid cathodes of different
compositions and designs are prepared and investigated
regarding their properties and the storage mechanism using
electrochemical analyses combined with operando XRD and
extensive materials characterization, including scanning
electron microscopy and energy-dispersive X-ray
spectroscopy. Finally, hybrid cathodes with higher areal
capacity are prepared and investigated regarding rate
performance. Model-based analysis of the results reveals
design criteria and material properties required to achieve
synergistic effects between the components in hybrid
cathodes. These insights lay the foundation for a new type
of battery with advantageous properties in terms of cost,
environmental friendliness, and electrochemical
performance.},
