| titleOfInvention | Lithium ion battery cathode water system binder composition and preparation process thereof |
| abstract | The invention discloses a lithium ion battery cathode water system binder composition and a preparation process thereof, wherein the composition comprises the following components: the hydrophilic monomer, the lipophilic monomer and the unsaturated carbon chain are polymerized under the action of an emulsifier, and the preparation method comprises the following steps: weighing a polybasic alkyl salt serving as an emulsifier; dissolving an emulsifier in water, and introducing protective gas to drive oxygen; adding an initiator into an emulsifier for uniform mixing; mixing and stirring a hydrophilic monomer, a lipophilic monomer and an unsaturated carbon chain to obtain a mixed monomer; dropwise adding an emulsifier into the mixed monomer, and continuously stirring after all the emulsifier is added; the final mixed binder is passed through a 50 to 400 mesh screen. Compared with the traditional method, the invention improves the physical and chemical properties of the emulsion, the electrical property and the binding power of the emulsion, provides excellent flow extension property of the emulsion, improves the coating rate of the binder on the surface layer of the negative electrode, increases the microscopic effective binding site of the negative electrode material and reduces the using amount of the binder of the negative electrode of the lithium ion secondary battery through the innovation of the process and the formula. |
