      abstract     = {Solvent co-intercalation, that is, the combined
                      intercalation of ions and solvent molecules into electrode
                      materials, is an additional but much less explored lever for
                      modifying the properties of metal-ion battery electrodes
                      (metal = Li, Na, Mg, etc.). Knowledge on solvent
                      co-intercalation is relatively scarce and largely limited to
                      graphite anodes, for which in sodium-ion batteries, the
                      co-intercalation of glyme molecules is fast and highly
                      reversible. The use of co-intercalation for cathode active
                      materials (CAMs) remains much less explored. Here we
                      investigate for a series of sodium-layered sulfide CAMs
                      (Na$_x$MS$_2$, M = Ti, V, Cr and mixtures) under which
                      conditions solvent co-intercalation occurs and how this
                      process impacts the phase behaviour, electrode breathing,
                      redox potential and cycle life compared to ‘Na$^+$-only’
                      intercalation. Co-intercalation is a complex process that
                      can, for example, cause opposing fluxes, meaning that
                      solvents intercalate into the CAMs while sodium ions
                      simultaneously deintercalate. Co-intercalation leads to
                      layered structures that can include different amounts of
                      confined solvated ions, ions and unbound solvent molecules.
                      It is an approach to designing structurally diverse, layered
                      materials with potential applications for batteries and
                      beyond.},
