Abstract
(EN)
This method for producing an aqueous electrode slurry for lithium ion batteries is a production method for an aqueous electrode slurry that contains an electrode active material which is selected from among a positive electrode active material and a negative electrode active material, an aqueous binder, a thickening agent and an aqueous medium; and this method for producing an aqueous electrode slurry for lithium ion batteries comprises a step for obtaining a sieve-passed fraction (q) of a thickening agent powder, which contains a cellulose-based water-soluble polymer, by sieving the thickening agent powder and a step for preparing an aqueous electrode slurry by mixing an electrode active material, an aqueous binder, the sieve-passed fraction (q) and an aqueous medium with each other.
