Binder composition for electrochemical element, conductive material dispersion for electrochemical element, slurry for electrochemical element electrode, electrode for electrochemical element and electrochemical element

摘要

PROBLEM TO BE SOLVED: To provide a binder composition for an electrochemical device capable of forming an electrode having excellent viscosity stability and excellent peel strength. A polymer containing a nitrile group-containing monomer unit, N-methyl-2-pyrrolidone, and a halogenated hydrocarbon are contained, and the content of the halogenated hydrocarbon is the content of the polymer. It is 2 mass ppm or more and 400 mass ppm or less. [Selection diagram] None
