Abstract
Statistical analysis has been presented of potentiodynamic measurements of composite anodes based on the ethylene-propylene terpolymer binder. A series of 20 potentiodynamic measurements has been carried out of three composite samples differing in the content of carbon black, an electric conducting component. Statistical analysis has been carried out of current density values for seven assumed potentials. The distribution function has been determined for obtained values, as well as the standard deviation and the absolute error range. It has been shown that the presented methodology can be used for evaluation of electrochemical properties of conducting composites and an advantageous effect of the highly conducting carbon black has been stated.
