摘要

PROBLEM TO BE SOLVED: To provide a method for producing a composite particle for an electrochemical element electrode, capable of obtaining a composite particle for an electrochemical element electrode which has a stable quality even when spraying is performed for a long time.SOLUTION: A method for producing a composite particle for an electrochemical element electrode includes the steps of: obtaining a slurry comprising an electrode active material and a binder dispersed or dissolved in a solvent; and spraying the slurry to be granulated. In the method, the viscosity of the slurry at 25°C is 1,500 mPa s or less when a shear rate is 1 sec, and 500 mPa s or less when a shear rate is 200 sec.SELECTED DRAWING: None
