COMPOSITE PARTICLES FOR ELECTROCHEMICAL DEVICE ELECTRODE, ELECTROCHEMICAL DEVICE ELECTRODE, ELECTROCHEMICAL DEVICE, METHOD FOR MANUFACTURING COMPOSITE PARTICLE FOR ELECTROCHEMICAL DEVICE ELECTRODE, AND METHOD FOR MANUFACTURING ELECTROCHEMICAL DEVICE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide composite particles for an electrochemical device electrode, by which an electrode low in basis weight and high in thickness accuracy can be manufactured.SOLUTION: Composite particles for an electrochemical device electrode are produced by spraying and solidifying a slurry containing an electrode active material and a binding resin. In a particle diameter distribution on a number-of-particles basis, which is obtained by particle diameter measurement according to laser light diffraction, particles of 40 μm or smaller account for 50% or less of all the particles.SELECTED DRAWING: None
