Mixture Powder For Dry Electrode, And Dry Electrode For Electrochemical Device Comprising Same

Abstract: A mixture powder for an electrode according to the present invention has a low tap density and a low tap compression ratio, excellent flowability, and low generation of fine powder. Accordingly, when manufacturing a dry electrode film by a roll-to-roll continuous process, processability is improved, such as a reduction in contamination of manufacturing equipment by means of the powder. In addition, since a bridging phenomenon is prevented when the mixture powder is introduced into equipment, the manufactured dry electrode film has a low pinhole generation rate. Accordingly, the dry electrode film obtained from the mixture powder for an electrode according to the present invention has excellent mechanical strength, such as a high tensile strength and elongation at break.
