Abstract: A method for evaluating the dispersibility of a conductive material. The method allows determination of the dispersibility of a conductive material in an electrode as a quantitative value. Particularly, a conductive material zone is defined from the result (2D mapping image) obtained by subjecting an optional predetermined cross-section of electrode active material layer to 2D-scale visual image processing, and then the circumference and area of the portion defined as the conductive material zone are calculated. In this manner, the dispersibility of the conductive material can be represented quantitatively.
