The Conductivity of EmimCl and BmimPF6 Ionic Liquids for Limited Range of Temperature (25 to 75 °C) Under Optimal Electrolyte Combination Conditions

The purpose of this study was to evaluate the ionic conductivity as a function of temperature, range (25 to 75°C) in the imidazolium-based ionic liquids 1-ethyl-3-methylimidazolium chloride (EmimCl) and 1-butyl-3-methyl imidazolium hexafluorophosphate (BmimPF6) of different volume percentages under...

Summary:The purpose of this study was to evaluate the ionic conductivity as a function of temperature, range (25 to 75°C) in the imidazolium-based ionic liquids 1-ethyl-3-methylimidazolium chloride (EmimCl) and 1-butyl-3-methyl imidazolium hexafluorophosphate (BmimPF6) of different volume percentages under optimal electrolyte combination conditions. The findings revealed that when 1% EmimCl or 1% BmimPF6 was applied, conductivity decreased significantly in relation to the Kohlrausch relationship. When 1% EmimCl or 2% BmimPF6 was added, the study showed the highest coefficient of alpha (α), while beta (β) was the lowest coefficient for temperature. In conclusion, the influence of the change in volume percentage on the conductivity is weakened by temperature control.
