To provide a negative electrode mixture in which a negative electrode active material is sufficiently dispersed and an electrode having less variations in thickness and density can be made, and a lithium secondary battery using the same.
The negative electrode mixture comprises one kind or more of dispersants selected from an organic colorant derivative having an acid functional group or a triazine derivative having an acid functional group, and the negative electrode active material, and the lithium secondary battery is formed using the negative electrode mixture. By the one kind or more of dispersants selected from an organic colorant derivative having an acid functional group or a triazine derivative having an acid functional group, the negative electrode active material and a carbon material as a conductive assistant are carried out covariance to manufacture the negative electrode mixture.
