Electrochemical Window of l-Butyl-3-Methylimidazoliuiii Hexafluorophosphate

Room-Temperature Ionic Liquids, RTILs are liquids that compose entirely of ions
and exist in the liquid state at room temperature. l-Butyl-3-Methylimidazolium
Hexafluorophosphate, (CsHis^FeP) or BMM-PF6 is one of RTILs which is used in a
wide variety of applications due to its attractive physical-chemical properties such as
having wide electrochemical window value. The electrochemical window of an ionic
liquid is the voltage range between whichthe substance doesn't get oxidized or reduced.
This range is important for the efficiency of an electrode. Out of this range water gets
electrolyzed, spoiling the electrical energy that is intended for another electrochemical
reaction. The objective of this project is to determine the electrochemical window of
ionic liquid that is l-Butyl-3-Methylimidazolium Hexafluorophosphate. The
electrochemical window is measured by the reduction of the cation and the oxidation of
the anion. The electrochemical window value can be obtained by running linear sweep
voltammetry experiment. The electrochemical window value obtained from the
experiment is about 2.3 V.
