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.

Concentration $($Li$+)$ in LiTFSI

Top plot is from experimental data. $2$ plots below are from simulation $($see chart title and axis$).$

Mol$\%$ is of the LiTSFI content in solid solutions $($LiTFSI$)$x$($SN$)1-$x$.$ How the Li$+$ ionic

conductivity varies with composition over this range? Based on these simulations, which

$($LiTFSI$)$x$($SN$)1-$x composition would you suggest as a fast$-$ion conducting solid

electrolyte for battery applications.
