PROCÉDÉ ET DISPOSITIF D'ÉVALUATION DE LA STABILITÉ DE PHASE D'UNE SUSPENSION DE MÉLANGE POUR ÉLECTRODE

摘要

Provided is a method for evaluating phase stability of electrode mixture slurry, including the steps of: (S1) introducing electrode mixture slurry to a rheometer; (S2) applying a first shear rate to the electrode mixture slurry; (S3) applying a second shear rate after applying the first shear rate, wherein the second shear rate is higher than the first shear rate; (S4) applying a third shear rate after applying the second shear rate, wherein the third shear rate is equal to the first shear rate; and (S5) comparing the shear viscosity at the first shear rate with the shear viscosity at the third shear rate. An apparatus for evaluating phase stability of electrode mixture slurry is also provided.
