Abstract
A method for measuring the properties of an anode slurry, including preparing a kneaded anode slurry, measuring an insertion length of a measuring bar, and calculating a kneading energy of the anode slurry. Specifically, the method being capable of evaluating the degree of adsorption among a conductive material, an active material, and carboxy methyl cellulose (CMC) in a kneaded state of the anode slurry.
Claims11
A method for measuring physical properties of an anode slurry, comprising:
- (S1) preparing a kneaded anode slurry containing CMC (carboxy methyl cellulose) as a thickener;
- (S2) inserting a first end of a measuring bar into the kneaded anode slurry and measuring an insertion length of the measuring bar inserted into the kneaded anode slurry and further measuring load values corresponding to the insertion length;
- and
- (S3) integrating the measured load values corresponding to the measured insertion length to calculate a kneading energy, and determining a dispersion characteristic of the anode slurry based on the kneading energy.
