AI Technical Summary
Existing lithium battery binder SBR is prone to localized excessive concentration and uneven mixing during the mixing process, which affects the performance of the electrode slurry and easily causes blue floating phenomenon.
The method of bottom feeding and diversion dispersion, combined with a stirring mechanism, is adopted. The binder is introduced through the bottom of the tank and evenly dispersed by the diversion mechanism. Combined with the cooling of the heat exchange medium, the binder is ensured to be evenly distributed and quickly fused in the slurry.
This achieves uniform distribution of the binder in the slurry, reduces blue floating phenomenon, and improves mixing efficiency and electrode slurry quality.
