CARBON MATERIAL DISPERSION SOLUTION, AND SLURRY COMPOSITION FOR SECONDARY BATTERY NEGATIVE ELECTRODES IN WHICH SAME IS USED

WIPO Patent Application WO/2024/095757

A1

The purpose of the present invention is to provide: a carbon material dispersion solution which does not adversely affect other blended components, is effective against microorganism including a broad spectrum of bacteria, fungi and yeast, exhibits a high preservative and antibacterial effect in a small amount for a long period with high sustainability even under any environments, and therefore can highly achieve both of dispersibility and storge stability; and a slurry composition for secondary battery negative electrodes, in which the dispersion solution is used and which is suitable for the production of a battery such as a lithium ion battery and an electrode.　The carbon material dispersion solution according to the present disclosure comprises at least a carbon material containing carbon nanotubes, a dispersing agent, a preservative agent and a liquid medium, and is characterized in that the preservative agent comprises a triazine-based compound and at least one component selected from group A.　Group A: a iodopropargyl-based compound, a pyridine-based compound, a pyrithione-based compound, an oxyquinoline-based compound, a benzothiazole-based compound, an isothiazoline-based compound, and a dithiol-based compound.
