摘要

PROBLEM TO BE SOLVED: To provide a composite particle for an electrochemical element electrode, capable of obtaining an electrode active material layer excellent in film thickness accuracy, excellent in adhesion between the obtained electrode active material layer and a collector, and further capable of being collected at a high yield.SOLUTION: Composite particles for an electrochemical element electrode can be obtained by solidifying liquid droplets of a slurry in a cationic polymer aqueous solution to form particles, the slurry containing an electrode active material, a binding resin and a water-soluble polymer, and then by separating the solidified particles from the cationic polymer aqueous solution to be dried.SELECTED DRAWING: None
