ELECTROCHEMICAL-ELEMENT BINDER COMPOSITION, ELECTROCHEMICAL-ELEMENT SLURRY COMPOSITION, ELECTROCHEMICAL-ELEMENT FUNCTIONAL LAYER, AND ELECTROCHEMICAL ELEMENT

摘要

Provided is a binder composition for an electrochemical device that can improve cycle characteristics of an electrochemical device including a functional layer that is formed using a produced slurry composition for an electrochemical device. The binder composition for an electrochemical device contains a polymer A and a solvent. The polymer A includes a nitrogen-substituted amide group-containing monomer unit and a hydroxyl group-containing monomer unit. The content of the nitrogen-substituted amide group-containing monomer unit in the polymer A is not less than 10 mass% and not more than 80 mass%, and the content of the hydroxyl group-containing monomer unit in the polymer A is not less than 10 mass% and not more than 70 mass%.
