摘要：

In this paper the structure and electrochemical stability of ionic liquid analogue based on choline chloride and urea is reported. The microscopic structure of the ionic liquid analogue is preliminary investigated by Fourier transform infrared spectroscopy (FTIR). The cyclic voltammetry behavior of ionic liquid analogue is studied. The decomposition products of chlorine gas and triethylamine are observed. Possible mechanisms for the formation of these products are given. The effects of temperature and cycle index on electrochemical behavior are discussed. The electrochemical impedance spectroscopy behavior on Pt electrode is investigated at temperature of 60 degrees C, 80 degrees C and 100 degrees C ranging from 0.001 to 10(5) Hz. The equivalent circuit diagram and the electrochemical element values are given. (C) 2012 Elsevier Ltd. All rights reserved.
