To explore the relationship between the number of transition metals in the simulation and short-range order suppression in a more experimentally relevant compositional space we run additional Monte Carlo simulations on fluorinated lithium-excess disordered rock salt materials. We simulate all equimolar charged balanced compositions maintaining an average transition metal oxidation state of 3+ in the compositional range Li 1 + x MO 2 F x , where x ∈ {0.4, 0.5, 0.6, 0.7, 0.8}. The transition metals included remain Mn(III), Cr(III), Fe(III), Ni(II) and Ti(IV). Figure shows the change in the amount of lithium that is connected to the longrange percolating network 0-TM network-we define this as the active lithium, Li active -as the number of transition metals increases, averaged over all values of x. Increasing the number of transition metals on the cation sublattice generally results in an increase in Li active . However, the increase in the size of the lithium diffusion network levels off as the number of transition metals increases mirroring the short-range order suppression behavior highlighted in Figure . This suggests that the observation of "diminishing returns" of short-range order suppression noted for the LiMO 2 system is extensible to the lithium-excess oxyfluorides.
