The invention discloses an emulsion polymerization polymer dispersant for lithium battery CMC, which is mainly composed of unsaturated monomer, water, emulsifier and water-soluble initiator. The emulsion polymerization is composed of various unsaturated monomers and water in The unsaturated monomers include but are not limited to: acrylic acid, methacrylic acid, methyl methacrylate, styrene, vinyl acetate, butyl acrylate, One or more of isooctyl acrylate, acrylamide, N-methacrylamide, and the main chain of the polymer dispersant is a -C-C-bond. The present invention uses a simple and environmentally friendly method to obtain a polymer dispersion that can be designed in advance on the main chain of the polymer skeleton, is better than CMC and is more suitable for lithium batteries, and can improve the performance of existing lithium batteries. agent to replace the widely used CMC dispersant today. |
