Ionic liquids are often mentioned as chemical compounds fulfilling the principles of green chemistry. An indisputable advantage of this type of compounds is the possibility of changing their physical or chemical properties by modifying a cation or an anion [1÷5].

Thanks to a number of unique properties, including high conductivity, thermal and chemical stability, low volatility or low toxicity, they are used in various fields of chemical industry, including electrochemistry. They are used among others in galvanotechnical processes, electrochemical synthesis of conductive polymers, supercapacitors, lithium-ion batteries and other electrochemical cells. [6÷9].
