P$.$S$.$ Whitfield et al$.,$ Solid State lonics $181(2010)740$ suggested the following phase

diagram

Fig. $5.$ Composition$/$temperature phase diagram for the succinonitrile:LiTFSI system

heated from $-100C$ constructed from the XRD data.

Top plot is from experimental data. $2$ plots below are from simulation $($see chart title$).$ Mol$\%$

is of the LiTSFI content in solid solutions $($LiTFSI$)$x$($SN$)1-$x$.$ whether simulations of

$($LiTFSI$)$x$($SN$)1-$x models using COMPASSIII yield a similar phase diagram as the one

observed experimentally? Explain your criteria for identifying the phase transitions in

these simulations.$|$
