4. Electrochemistry applications

4.1 Advantages and disadvantages

On the basis of these properties, we can summarize the advantages of ionic liquids for electrochemical applications as follows:

• their vapor pressure is negligible. They can also be used under atmospheric pressure over a much wider temperature window than that used for aqueous solutions;

• their electrical conductivity is good;

• their range of electroactivity is frequently wider (up to 6 V) than that of aqueous solutions (maximum 2 to 2.5 V in the best cases);

• they are thermally stable and not easily flammable either;

• Except in special cases, electrochemical processes in ionic...
