Room temperature ionic liquids or simply ionic liquids (some even call them molten salts) can act as a great solvent for electrochemistry but they bring along a challenge of what to use for the reference electrode. Traditional saturated calomel or Ag/AgCl reference electrodes use water as a solvent which can cause trouble for ionic liquids. For this purpose researchers have traditionally turned to psuedo reference electrodes in the form of Ag or Pt wires. These pseudo reference electrodes can suffer from drift or require the addition of a known standard at the end of an experiment.
A group of researchers at Technion – Israeli Institute of Technology in Haifa, Israel have devised a reference electrode for their particular ionic liquid but there is no reason you couldn’t develop something similar for your research.
