DISPERSANT COMPOSITION FOR ELECTROCHEMICAL DEVICE, CONDUCTIVE MATERIAL DISPERSION LIQUID FOR ELECTROCHEMICAL DEVICE, SLURRY COMPOSITION FOR ELECTROCHEMICAL DEVICE ELECTRODE AND METHOD OF PRODUCING SAME, ELECTRODE FOR ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL DEVICE
摘要：
A dispersant composition for an electrochemical device contains a polymer including a nitrile group-containing monomer unit and an alkylene structural unit. Upon measurement of the polymer contained in the composition by dynamic light scattering, a value (A) detected for volume-average particle diameter D50 is not less than 50 nm and not more than 800 nm, and one or more peaks are detected in a particle diameter range of not less than 5 μm and not more than 30 μm.
