| Outline of Final Research Achievements |
Solvate ionic liquids consisting of tetraglyme (G4) and Li salts were mixed with various solvents. In the solvate ionic liquids, G4 and Li cation form 1:1 complex cation [Li(G4)]. Hydrophobic ionic liquids, which have long alkyl chains in cation structure, were used as solvents to dissolve the solvate ionic liquids. The solvate structure of [Li(G4)] was kept in the mixed electrolyte owing to the weak interaction between solvate ionic liquid and hydrophobic ionic liquids. The water absorption of the electrolyte was suppressed by the addition of the hydrophobic ionic liquids. The mixed electrolytes composed of solvate ionic liquids and hydrophobic ionic liquids were applied to Li-air batteries. Li-air battery with mixed electrolyte can be operated under the humidified condition of 28% RH (relative humidity).
