METHOD FOR PRODUCING ELECTRODE, AND BATTERY

摘要

Provided is a technique which is capable of suppressing defects such as pin holes in an electrode. A negative electrode production step (S10) which comprises: a mixture production step (S11) wherein a paste-like negative electrode mixture (12a) that contains a negative electrode active material is produced; and a coating step (S12) wherein the electrode mixture (12a) is applied over the surface of a sheet-like negative electrode collector (11). The mixture production step (S11) comprises a step for adding a solvent to the negative electrode active material and a thickening agent that is in the form of a powder. The thickening agent is a carboxymethyl cellulose that has a maximum particle diameter of not more than 1/4 of the thickness of the electrode mixture (12a) applied to the negative electrode collector (11) in the coating step (S12).
