▎ 摘　　要

NOVELTY - Preparation of cathode slurry comprises weighing sodium carboxymethylcellulose, adding deionized water, and ultrasonic oscillating to dissolve; adding conductive agent, using planetary dispersion machine to disperse, and completely mixing; adding silicon carbon material, dispersing, and completely mixing; and adding styrene-butadiene rubber, dispersing, and completely mixing. USE - The method is used for preparation of cathode slurry for three-dimensional printing (claimed). ADVANTAGE - The method is simple, has short preparation time, reduces agglomeration mixing, improves the smoothness of printing, and has excellent performance.
