| Research Abstract |
Ionic liquids (ILs) have various interesting properties, for example, low vapor pressure, high electrical conductivity, chemical stability. Due to these unique properties, ILs can overcome the drawback of organic solvents such as high vapor pressure and flammability. Therefore it is attracted much attention as an electrolysis solution in Li ion battery. However it is known that molecular diffusion in IL is generally slow, because viscosities of ILs are higher than that of organic solvent. On the other hand, it has been reported that molecular diffusion in silicone oil is higher than that in organic solvents with the same viscosity. Therefore we expected that siloxane fanctional group may improve the rate of molecular diffusion. Our present purpose is analysis of transport property in silicone ionic liquids (SiILs) which is applicable to electrochemical devices. We applied the transient grating (TG) method in order to determine diffusion coefficients in SiILs.
