1.Mixing

1.1.Slurry stirring is the process of adding active materials, conductive carbon black, dispersants,

binders, additives, and other components to a mixing equipment in a certain proportion and

order. Under the mechanical actions such as agitation, kneading, and shearing generated by the

equipment, these components are mixed together to form a uniform, stable solid-liquid

suspension system suitable for coating.

Goal: Achieve uniformity and consistency at both macro and micro levels

 

1.2.Goal: Wettability, dispersion, and stabilization are the three key indicators of good slurry

 

1.3.Good wettability can reduce the difficulty of dispersion and improve mixing efficiency.

 

1.4.Mechanical stirring dispersion refers to the process of causing strong turbulent motion of the liquid flow through intense mechanical stirring, which leads to the breakup and suspension of particle aggregations.

 

1.5.The spatial hindrance effect of the dispersant adsorbed on the surface of the particles generates a strong repulsive force between the particles.
