Water-based polymeric adhesive for replacing oily PVDF adhesive for positive electrode of lithium ion battery and preparation method of water-based polymeric adhesive

The invention relates to the technical field of lithium ion battery adhesives, in particular to a water-based polymerization adhesive used for replacing an oily PVDF adhesive and used for a lithium ion battery positive electrode and a preparation method of the water-based polymerization adhesive. And carrying out high-molecular polymerization reaction at the temperature of 80 DEG C by using water as a medium and a carrier, so as to obtain the polymer adhesive. According to the invention, a simple and environment-friendly method is adopted to obtain a water-based polymer adhesive which is more environment-friendly, better in performance, better in quality and lower in cost than a PVDF (Polyvinylidene Fluoride) oily adhesive, and the water-based polymer adhesive is used for replacing the PVDF adhesive which is widely used in the existing lithium ion battery, is high in price, inconvenient to use, not environment-friendly and harmful to a human body. 本发明涉及锂离子电池粘合剂技术领域，具体的说是一种锂离子电池正极用代替油性PVDF粘合剂的水性聚合粘合剂及其制备方法，包括：
