Abstract: The object is to stabilize the dispersion of a conductive additive in a composition for a battery without deteriorating the conducting property of the conductive additive, and to thereby improve the battery performance of a battery produced by using the composition. Disclosed is a composition for a battery, which comprises: at least one dispersing agent selected from an organic dye derivative having a basic functional group, an anthraquinone derivative having a basic functional group, an acridone derivative having a basic functional group and a triazine derivative having a basic functional group; a carbon material as a conductive additive; and optionally an acid, a solvent, a binder, and a positive electrode active material or a negative electrode active material.

Abstract: A composition for a battery containing an electroconductive assistant improves battery performance of a battery produced using this composition as a result of achieving dispersion stabilization without inhibiting electroconductivity of the electroconductive assistant.
