Abstract
Thickener powder for a lithium-ion battery of the present invention is thickener powder that is used to thicken a water-based electrode slurry for a lithium-ion battery, the thickener powder includes a cellulose-based water-soluble polymer, and a content of a water-insoluble component in the thickener powder, which is calculated from Condition 1, is equal to or less than 1.0% by mass. (Condition 1: The thickener powder is dissolved in water, thereby obtaining a thickener aqueous solution having a concentration of 1.3% by mass. Next, the thickener aqueous solution is filtered using a filter having an average pore diameter of 1 μm. Next, the water-insoluble component remaining on the filter is dried, and a mass of the water-insoluble component is measured. Next, the content of the water-insoluble component in the thickener powder is calculated.)
