Characterization of electrode materials by Dielectric spectroscopy (CAT#: STEM-ST-0363-WXH)

The principle of this technique is to apply an AC signal of small amplitude to an electrode immersed into an electrolyte. The initial disturbance (applied) and the response of the electrode is compared by measuring the phase shift of the current and voltage components and by the measurements of their amplitudes.

Used to study the response of a sample subjected to an applied electric field of fixed or changing frequency. DS describes the dielectric properties of a material as a function of frequency.
