▎ 摘 要
NOVELTY - Lithium ion battery anode slurrying, comprises (1) adding 85-95 pts. wt. anode material, 0.5-5 pts. wt. conductive agent and 2-6 pts. wt. Polyvinylidene fluoride dry powder in sequence, and dispersing at high speed for 30-60 minutes, (2) adding N-Methyl-2-pyrrolidone solvent to make the solid content 70-80%, dispersing at medium speed for 30-60 minutes and dispersing at high speed for 60-90 minutes, (3) adding 0.5-3 pts. wt. carbon nanotube conductive agent, and dispersing at high speed for 30-60 minutes, and (4) adding the remaining N-Methyl-2-pyrrolidone to make the solid content 50-60%, where the viscosity 3000-8000 mPa/s, dispersing at a medium speed for 30-60 minutes, and obtaining a well-mixed anode slurry. USE - The method is useful for lithium ion battery anode slurrying. ADVANTAGE - The method greatly shortens the pulping process time, the pulping device has low requirement, and is suitable for industrial production of lithium ion battery.
