Abstract
The present invention discloses a method for determining dispersibility, comprising (a) selecting two random points (-') of an electrode material layer, (b) finding a difference Δof an absolute value of two voltage values by measuring voltages between the two points (-′) in different current directions, (c) selecting two other random points (-′ to n-n′, where n is an integer that is equal to or greater than 2) that are different from two points selected in the process (a) and, and repeating the processes (a) and (b) at least once to find Δto Δn, (d) finding a mean value of differences Δto Δn of the absolute values obtained by repeating the process (b) and the process (c), and (e) finding a standard deviation of Δto Δn from the mean value.
