DISPERSION SLURRY USING CARBON NANOTUBE AND LITHIUM ION SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode for a coating composition in which a suitable condition in a dispersion step of lithium ion battery electrode slurry can be determined by a numerical value and obtained performance of a battery can be improved.SOLUTION: Disclosed is a method of manufacturing electrode slurry for a positive electrode plate for a lithium ion secondary battery in which a carbon nanotube is used for at least a conductive material, and their carbon material and solvent are mixed and dispersed. Regarding carbon material dispersion slurry, an AC impedance value immediately after dispersion is controlled by a predetermined numerical value.
