▎ 摘　　要

NOVELTY - Aqueous conductive paste, prepared by (i) adding the conductive agent, binder, surfactant, abrasive and pure water into a stirrer in a mass ratio of (1-10%): (10-40%): (0.1-5%): (0.1-5%): (40-89.8%), stirring at 15-55℃ for 2-8 hours to obtain conductive coarse paste, and (ii) placing conductive coarse paste into a twin-screw extrusion homogenizer for continuously crushing and grinding at ≤ 65℃for 4-16 hours, and crushing and grinding the conductive particles in the conductive coarse paste to small particles with a D50 particle size of 0.1-2 μm, is claimed. USE - The paste is useful for preparing the porous aqueous coated aluminum foil (claimed). ADVANTAGE - The paste: significantly improves the adhesion between coating and aluminum foil, and tensile strength of the foil relative to mechanical punching. The laser microhole: makse the anode coating on the A/B side of the anode sheet conduct, so that the A/B side lithium (I) ion can flow through the microholes; avoids lithium (I) ion precipitation due to the collapse of the anode material crystals in the later cycle of the battery; directly bonds the anode coating on the A/B side to form a similar 'skeleton' structure; strengthens the adhesion and mechanical strength of the cathode coating; forms a dense film layer closely attached to the surface of the aluminum foil; further reduces the resistivity of the membrane area; avoids the phenomenon of powder falling and membrane peeling of the battery pole piece in the subsequent use process; and reduces the safety risk. The aluminum foil has improved physical and chemical performance, adhesive force and mechanical anode of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the porous aqueous coated aluminum foil with the aqueous conductive paste.
