BINDER COMPOSITION FOR ELECTRICITY STORAGE DEVICES, SLURRY FOR ELECTRICITY STORAGE DEVICE ELECTRODES, ELECTRICITY STORAGE DEVICE ELECTRODE, SLURRY FOR FORMING PROTECTIVE FILM, PROTECTIVE FILM, AND ELECTRICITY STORAGE DEVICE

摘要

This binder composition for electricity storage devices is characterized by containing: (A) particles of a polymer which contains a repeating unit (a) that is derived from a fluorine-containing compound and a repeating unit (b) that is derived from a polyfunctional (meth)acrylic acid ester; and (B) a liquid medium. This binder composition for electricity storage devices is also characterized in that one endothermic peak is observed within the temperature range from -30°C to 30°C and one endothermic peak is observed within the temperature range from 80°C to 150°C when differential scanning calorimetry (DSC) is carried out on the polymer particles (A) in accordance with JIS K7121.
