“…SCN is a plastic crystal at room temperature with a crystal-plastic crystal transition at -40 °C and plastic crystal-isotropic melt transition at 58 °C [20]. More importantly, SCN serves as an effective plasticizer to the polymer matrix as well as efficient ionizer to the lithium salt [21].…”

“…The disorder in this plastic-crystalline phase is associated with isomeric fluctuations and with large-angle molecular rotations in which the C-C bond orientation jumps from one diagonal position of the cubic cell to another. 13,[18][19][20] Below 233 K, pure SN displays a perfectly crystalline monoclinic phase without molecular motions nor isomerism. 20,21 In spite of the widespread belief that the orientational dynamic processes in plastic SN are beneficial to its ionic mobility, 20,22 no clear correlation has been found between both quantities.…”

We probe the ion conduction and the molecular dynamics in a pure and lithium-salt doped dinitrile molecular plastic crystal. While the diffusion of the Li + ions is decoupled from the molecular reorientational dynamics, in the undoped plastic crystal the temperature dependence of the mobility of dinitrile ions and thus of the conductivity is virtually identical to that of on-site molecular rotations. The undoped material is found to obey the Walden and Stokes-Einstein rules typical of ideal liquid electrolytes, implying that an effective viscosity against diffusion can be defined even for a plastic crystalline phase. These surprising results, never reported before in a translationally ordered solid, indicate that in this dinitrile plastic crystalline material the time scale of translational diffusion is perfectly correlated with that of the purely reorientational on-site dynamics.

Plastic crystal electrolytes formed by doping succinonitrile with lithium salts can potentially meet these requirements. In this study, succinonitrile doped with various lithium salts were characterized by differential scanning calorimetry, powder X-ray diffraction, conductivity measurements and in electrochemical studies. The much better conductivities and electrochemical performance of certain lithium salts in comparison to the others studied has been found to be correlated to their propensity to form crystalline adducts with succinonitrile at low molar concentrations. Of the lithium salts studied, only two which did not form crystalline adducts at low concentrations: lithium bistrifluoromethanesulphonylimide (Li[CF 3 SO 2 ] 2 N) and lithium tetrafluorborate (LiBF 4 ) had high enough conductivities at ambient temperature for evaluation in lithium cells. Contrary to prior predictions, both showed reasonable capacities, high coulombic efficiencies, and good capacity retention even with metallic lithium as the anode. Crown
