摘要

PROBLEM TO BE SOLVED: To provide composite particles for an electrochemical element electrode capable of producing an electrode having low weight per unit area and high thickness accuracy, at low costs.SOLUTION: The composite particles for the electrochemical element electrode is obtained by performing a step for obtaining coagulated particles by adding a non-miscible solvent, a surface active agent and coagulated liquid to a slurry containing an electrode active material and binding resin while the slurry is being agitated, and a step for filtering the coagulated particles, then drying them.SELECTED DRAWING: None
