Abstract
Official abstract text for this publication.
A method of manufacturing an electrode includes: forming wet granules; and forming an electrode mixture layer on an electrode current collector by rolling the formed wet granules. When the wet granules are formed, a conductive material and fine particles having a primary particle diameter of 20 nm or smaller are stirred and mixed with each other, and the stirred mixture and an electrode active material are stirred and mixed with each other. During the stirring when the wet granules are formed, a peripheral speed of a stirring blade included in a stirrer is 10 m/s or higher.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of manufacturing an electrode comprising: forming wet granules by mixing a conductive material, an electrode active material, a binding material, and a solvent; and forming an electrode mixture layer on an electrode current collector by rolling the wet granules, wherein when the wet granules are formed, the conductive material and fine particles having a primary particle diameter of 20 nm or smaller are stirred and mixed with each other, and a stirred mixture and the electrode active material are stirred and mixed with each other, and during the stirring when the wet granules are formed, a peripheral speed of a stirring blade included in a stirrer is 10 m/s or higher. 2 . The method according to claim 1 , wherein an amount of the added fine particles is 0.05 wt % or more and 1 wt % or less with respect to the electrode active material. 3 . The method according to claim 1 , wherein an amount of the added fine particles is 0.1 wt % or more and 0.5 wt % or less with respect to the electrode active material. 4 . The method according to claim 1 , wherein during the stirring when the wet granules are formed, the peripheral speed of the stirring blade is 15 m/s or higher. 5 . The method according to claim 1 , wherein the fine particles are alumina particles.
