DISPERSANT COMPOSITION FOR ELECTROCHEMICAL ELEMENT, ELECTROCONDUCTIVE MATERIAL DISPERSION FOR ELECTROCHEMICAL ELEMENT, SLURRY COMPOSITION FOR ELECTROCHEMICAL ELEMENT ELECTRODE AND METHOD FOR MANUFACTURING SAME, ELECTRODE FOR ELECTROCHEMICAL ELEMENT, AND ELECTROCHEMICAL ELEMENT

摘要

The present invention is a dispersant composition for an electrochemical element, the dispersant composition including a polymer that contains a nitrile-group-containing monomer unit and an alkylene structural unit. With regard to the polymer contained in the composition, when dynamic light-scattering measurement is performed on the polymer, the value (A) of the volume-average particle diameter D50 detected is 50-800 nm (inclusive), and at least one peak is detected in the particle diameter range of 5-30 μm (inclusive).
