The ionic conductivity and ion dissociation behavior of the next RTIL system consisting of The ionic conductivity and ion dissociation behavior of this RTIL system is shown in Figure . It also has a similar trend of ionic conductivity and ion dissociation with composition to the previous RTIL system. Among imidazolium-based cations with [OTF] - anion RTIL, the lowest alkyl chain length cation representing the ultimate ionic conductivity in EG, also the as the alkyl chain length increases, the composition of the RTIL in EG decreases (Figure ). Relative ion dissociation and ionic conductivity pattern with RTIL composition have a similar fashion resulting in the ξr, a significant parameter to represent the conductivity behavior pattern with composition (Figure ). Therefore, this RTIL system has the following trend of ionic conductivity,
