摘要

Problem to be solved: to provide a slurry composition excellent in the time course stability of the dispersed state, and to provide a dispersing agent composition for the electrochemical element capable of increasing the rate characteristic and the high temperature storage characteristic of the obtained electrochemical element, and a material dispersion liquid for the electrochemical element including the same.Solution: a dispersing agent composition comprising a polymer containing a nitrile group monomer unit and an alkylene structural unit comprising an electrochemical element.The polymer contained in such a composition is a dynamic light scattering measurement of the polymer, wherein the value (a) of the volume average particle diameter D50 detected is 50 nm or more and 800 nm or less, and also 5 μ More than μ At least one peak is detected in the particle diameter range of M or less.No selection
