METHOD FOR PRODUCING ELECTRODE, AND BATTERY |
摘要 |
Disclosed is a technique capable of minimizing defects, such as pinholes, in an electrode. A negative electrode forming step includes a mixture preparing step for preparing a paste-like negative electrode mixture containing a negative electrode active material, and an applying step for applying the electrode mixture onto the surface of a sheet-like negative electrode current collector. The mixture preparing step includes the step for adding a solvent to a thickener in powder form and the negative electrode active material. The thickener is carboxymethyl cellulose having a maximum particle size equal to or less than 1/4 of the thickness of the electrode mixture applied onto the negative electrode current collector in the applying step. |

1. A method for producing an electrode, comprising:
a mixture preparing step for preparing a paste-like electrode mixture containing an active material; and an applying step for applying the electrode mixture onto a surface of a sheet-like current collector, wherein the mixture preparing step includes a step for adding a solvent to a thickener in powder form and the active material, and wherein the thickener is carboxymethyl cellulose having a maximum particle size equal to or less than ¼ of a thickness of the electrode mixture applied onto the current collector in the applying step, and wherein the thickener has a degree of etherification of 0.65 or more. |
