摘要： A SAP evaluation apparatus includes: a main body installed with a lifting bar that is raised or lowered; a container portion installed under the lifting bar in the main body and having an internal containing space for containing an absorber; an operating portion connected to the lifting bar and having a lifting plate that is raised or lowered within the containing space and applies pressure to the absorber and an injection portion for injecting an ink in the direction of the absorber; a dispersion measurement portion for measuring the dispersion of the ink through the absorber; and a controller installed at the main body to measure absorption of the ink into the absorber and measure swelling capacity of the absorber while the ink is injected into the absorber.

摘要： A method for predicting the likelihood of coagulation of active material particles contained in a slurry for electrode preparation includes measuring rheological properties before and after the slurry is subjected to a shear. The estimation method enables a prediction of filter clogging with a slurry, and thus makes it possible to estimate the likelihood of filter clogging with a slurry without passing the slurry directly through the filter, thereby improving the efficiency of a battery manufacturing process.
