Electrolyte Domain of Electrochemical Stability

The potential window over which the electrolyte is electrochemically stable may be estimated using a polarizable (blocking) electrode, such as platinum. The current is monitored as a function of the electrode potential, and the zero-current region (or nearly zero-current) defines the domain of electrochemical stability of the electrolyte. Of course, this potential range will depend mainly on the nature and the surface of the electrode (roughness). 

The most common techniques for testing electrodes are sweep voltammetry, galvanostatic poten-tiometry, rotating disk electrochemistry, and impedance spectroscopy. Detailed information about these techniques may be found in most classical electrochemical textbooks [6-13], and we will present here the basics of these techniques.
