METHOD FOR EVALUATING DISPERSION STATE OF ORGANIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To evaluate a dispersion state of a specific organic material in a battery component with high sensitivity and simply regarding an evaluation method for the dispersion state of the specific organic material in the battery component.

SOLUTION: The evaluation method is constituted in such a way that a coloring treatment is executed by bromine or ruthenium regarding the specific organic material which is hardly discriminated by elements in the battery component and which is constituted mainly of three elements of H, O and C, that a solid material is spatially and elementally analyzed and measured, and that the dispersion state of the specific organic material is evaluated.
