Method for manufacturing of slurry for negative electrode

Abstract

The present invention relates to a method of preparing a negative electrode slurry, and, specifically, the present invention provides a method of preparing a negative electrode slurry which includes the steps of preparing a first negative electrode slurry including a silicon-based active material, a carboxymethyl cellulose, and a styrene-butadiene rubber, and a second negative electrode slurry including a graphite-based active material, a conductive agent, a styrene-butadiene rubber, and a carboxymethyl cellulose (step 1), and mixing the first negative electrode slurry and the second negative electrode slurry which are prepared in step 1 (step 2).
