摘要

The method for producing an aqueous electrode slurry for a lithium ion battery of the present invention includes water for a lithium ion battery containing an electrode active material selected from a positive electrode active material and a negative electrode active material, an aqueous binder, a thickener, and an aqueous medium. A method for producing a system electrode slurry, wherein a thickener powder containing a cellulose-based water-soluble polymer is sieved to obtain a passing portion (q) of the thickener powder through the sieve, and an electrode active material. The step of preparing an aqueous electrode slurry by mixing the aqueous binder, the above-mentioned sieve-passing portion (q), and the aqueous medium is included.
