Abstract

The disclosure provides a tetrafluoroethylene-based polymer composition for a binder for an electrochemical device, capable of reducing the resistance of an electrochemical device and yielding a mixture sheet with excellent adhesion to a substrate, and a binder for an electrochemical device, an electrode mixture, an electrode, and a secondary battery each containing the composition. Provided is a tetrafluoroethylene-based polymer composition for use in a binder for an electrochemical device, the tetrafluoroethylene-based polymer composition containing a polar group in an amount of less than 0.020 meq/g based on the tetrafluoroethylene-based polymer composition, being non melt-processible, and having an apparent density of less than 0.50 g/mL.
