IONIC PLASTIC CRYSTALS, COMPOSITIONS COMPRISING SAME, METHODS FOR MANUFACTURING SAME AND USES THEREOF

The present technology relates to an ionic plastic crystal comprising at least one delocalized anion paired with at least one an organic guanidine, amidine or phosphazene organic superbase-derived cation for use in electrochemical applications, particularly in electrochemical accumulators such as batteries, electrochromic devices, and supercapacitors. The present technology also relates to an ionic plastic crystal composition, an ionic plastic crystal-based solid electrolyte composition, an ionic plastic crystal-based solid electrolyte, an electrode material comprising the ionic plastic crystal or the ionic plastic crystal composition. Their uses in electrochemical cells and electrochemical accumulators as well as their processes of manufacturing and an NHO-stabilized intermediary ion-neutral complex are also described.
