Document Type and Number:
Japanese Patent JP2023096879
Kind Code:
A
Abstract:
To provide a slurry composition for an electrode film, having an excellent dispersibility and an excellent stability.SOLUTION: A manufacturing method of a slurry composition for an electrode film is provided, including a step of preparing a carbon nano-tube dispersion liquid including a carbon nano-tube (A), a polymer (B) including a structural unit containing a nitrile group and an amide-based organic solvent (C), and further including: a step of preparing a slurry precursor for an electrode film including an active material (D), a low-molecular-weight acid compound (E) having a molecular-weight less than 10,000, a fluorine-based polymer (F), and an amide-based organic solvent (C'); and a step of mixing the carbon nano-tube dispersion liquid with the slurry precursor for the electrode film.SELECTED DRAWING: Figure 1
