▎ 摘  要

NOVELTY - Conductive material linear dispersion slurry comprises a conductive material, a dispersing agent for dispersing the conductive material, and a solvent mixed with the conductive material and dispersant comprising a cellulose-based compound and a vinyl-based or acrylic-based compound, where the weight ratio of the cellulose-based compound and vinyl-based or acrylic-based compound is 25:1-1:25. USE - The conductive material linear dispersion slurry is useful for electrode for secondary battery (claimed). ADVANTAGE - The dispersion slurry prevents or minimizes damage to carbon nanotubes, and has improved dispersion characteristics of carbon nanotubes, and has relatively high carbon nanotubes content, and relatively low viscosity, and is easy to easily manufacture by relatively simple process, and the electrode has excellent performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an electrode for a secondary battery manufactured by applying the conductive material linear dispersion slurry; and (2) a method for manufacturing the conductive material linear dispersion slurry, involving preparing a mixed solution using the above components of the slurry, and high-pressure dispersing the mixed solution using a high-pressure disperser having an operating pressure of 200 bar or more.
