| titleOfInvention | Lithium ion battery positive plate and preparation method thereof |
| abstract | The invention discloses a lithium ion battery positive plate and a preparation method thereof, and belongs to the technical field of lithium ion batteries. The lithium ion battery positive plate comprises a positive electrode material and an aluminum-based current collector, wherein the positive electrode material comprises a positive active material, a conductive material and a bonding material, and the bonding material is a composite water-soluble adhesive containing a water-soluble adhesive and a phosphate radical-containing compound. The invention utilizes common water-soluble adhesive and adds phosphate radical compound to prepare composite water-soluble adhesive, phosphate radical and organic compound of the water-soluble adhesive form stable chemical bond to achieve the purposes of increasing the strength of the polar plate and preventing polar plate cracks, wherein metal ions have the problem of preventing corrosion of the aluminum-based collector plate caused by the reaction of LR-NCM surface and water. The composite water soluble adhesive can effectively improve the corrosion resistance of the aluminum-based current collector of the positive plate in LR-NCM positive water-based slurry, improve the crack resistance of the plate, and prolong the electrochemical cycle life of the battery. |
