Japanese Patent JPWO2022118562
Kind Code:
A1
Abstract:
A method for manufacturing an electrically-conductive paste includes: bringing carbon nanotubes (CNT) and a solvent into contact with each other so that a wetting rate is 25 to 125%; kneading, by using a planetary stirring machine, a mixture containing the CNT and the solvent obtained by impregnating the CNT with the solvent, to obtain a kneaded product in a paste state; and then performing dispersion processing on a dilution obtained by mixing a solvent into the obtained kneaded product. It is possible to manufacture an electrically-conductive paste that: contains CNT at a high concentration even when the amount of the dispersant is small; has a low viscosity; and is easy to handle. This electrically-conductive paste can be mixed with a positive electrode active material for a lithium-ion secondary battery, so as to produce a positive electrode mixture.
