The present invention relates to the field of lithium ion battery separator production technology, and more particularly, to an aqueous PVDF slurry with high tackiness, a manufacturing method, and its application, and specifically, 3 to 7% dispersant, 1 ~5% wetting agent, 5~10% adhesion aid, 0.5~3% antifoaming agent, 0.1~3% anti-settling agent, 15~25% PVDF and 0.05~2.5% silicon carbide, the remainder being water, The addition amount and the addition amount of PVDF are calculated from 1:10 to 300 by mass ratio. By uniformly dispersing SiC in the PVDF long-chain, a large amount of microcapacitor structure is formed, and due to the high thermal conductivity and crosslinking role of SiC, the external heat is quickly transferred to the inside of the PVDF slurry, and the PVDF slurry Accelerate the adhesion of the aqueous PVDF slurry and further improve the adhesion performance of the aqueous PVDF slurry to obtain an aqueous PVDF slurry with a relatively thin coating layer and relatively good adhesion. |
