Beschreibung
Zusammenfassung:	Provided is a fluoropolymer composition for use in an electrochemical device binder, the fluoropolymer composition being homogenously mixable with powder components in electrochemical devices and being capable of providing a mixture sheet having excellent strength and excellent flexibility. Also provided are an electrochemical device binder, an electrode mixture, an electrode, and a secondary battery each containing the fluoropolymer composition. The present disclosure relates to a fluoropolymer composition for use in an electrochemical device binder, the fluoropolymer composition containing a fluoropolymer. The fluoropolymer contains two or more tetrafluoroethylene-based polymers. The fluoropolymer is contained in an amount of 90% by mass or more relative to the fluoropolymer composition.
