Method For Measuring Dispersion Degree Of Conductive Material In Electrode For Electrochemical Device
Abstract: A method for evaluating a dispersion degree of a conductive material, according to the present invention, may confirm the dispersibility of a conductive material in an electrode as a quantitative value. Specifically, an arbitrary predetermined cross section of an electrode active material layer is subjected to a visual image processing of a two-dimensional scale to define a conductive material region from an acquired result (a 2D mapping image), and to calculate the circumference and the area of a portion defined as the conductive material region, to thereby quantitatively represent a degree of dispersion of the conductive material.
