Document Type and Number:
WIPO Patent Application WO/2023/163013
Kind Code:
A1
Abstract:
One example of the method for producing a positive electrode mixture slurry according to the present invention comprises: a first step in which a first slurry is prepared by kneading a positive electrode active material, a binder and a dispersion medium; and a second step in which a second slurry is prepared by adding a conductive agent and a dispersant to the first slurry and kneading the resulting mixture. In the second step, the kinetic energy applied to the slurry is set higher than those in the other steps. The production process of the positive electrode mixture slurry may comprise a third step in which a dispersant is added to the second slurry and the resulting mixture is kneaded.
