Outline of Final Research Achievements

Generally, an ionic liquid (IL) is defined as a salt having a melting point lower than 100 oC. They have a very low volatility, are flame retardant, and possess relatively high ionic conductivities. Since very few reports of ionic liquid having a plurality of positive charges in a molecule, we tried to prepare some kinds of salt having a multi ammonium group. We have clarified the physicochemical properties of all of the salt synthesized but, any salts did not form ionic liquid at room temperature. On the other hand, the multi cationic salts showed higher capacitance as an electrolyte for electric double layer capacitor than that of mono charge salt at the same molar concentration.
