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 is from simulation. 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.
