Apparatus and method of manufacturing dry electrode

Abstract

A method of manufacturing a dry electrode includes mixing a dry electrode active material, a conductive material, and a binder through a mixer, wherein mixing the dry electrode active material, the conductive material, and the binder includes controlling a gap between blades configured to be rotatable in the mixer and a chamber wall of the mixer during mixing. The gap is adjusted based on the stage of mixing, with specific gap values for a coating time to complex the conductive material with the active material, a dispersion time to uniformly disperse the binder, and a fibrillization time to form a network between the components. The method may also include an optional chopping time. An apparatus for manufacturing a dry electrode is also disclosed, featuring a mixer with adjustable blades and a chamber for controlling the gap during the mixing process. The apparatus further includes a motor, shaft, and electric cylinders for blade movement, providing precise control over the mixing conditions.
