  "textContent": "The present invention is directed to an ambient temperature molten salt as non-aqueous electrolyte. The molten salt comprises a cation of a guanidine moiety and an anion. The cation is selected from alkyl groups, alicyclic groups, or aromatic groups attached asymmetrically to guanidine. An exemplary salt is tetramethylguanidinimum bis-trifluoromethanesulfonyl imide, which is liquid at ambient temperature and only slightly soluble in water. The salt is prepared by bringing together two aqueous salt solutions, one containing tetramethylguanidine hydrochloride, and the other containing lithium bis-trifluoromethanesulfonyl imide. The electrolyte is useful with electrochemical devices such as primary and secondary electrochemical cells and capacitors, such as of the electrolytic and electrolytic/electrochemical hybrid types.",
