The positive electrode slurry mainly comprises a binder, a conductive agent, a positive electrode material and the like; the cathode slurry is also similar and mainly comprises a thickener, a binder, carbon powder or other cathode materials and the like. The preparation of the anode slurry and the cathode slurry comprises a series of processes of mixing, dissolving, rubbing, dispersing and the like between liquid and liquid, between liquid and solid materials, between solid and solid particles, and the process is accompanied by the change of parameters such as temperature, viscosity, granularity, viscosity and the like. The mixing and dispersing process of the lithium ion battery slurry can be divided into a macroscopic mixing process and a microscopic dispersing process, and the two processes are always accompanied with the whole process of preparing the lithium ion battery slurry. The slurry is typically prepared through the following stages:
① Mixing the dry powder. The particles are contacted in the form of point-to-point, point-to-plane and point-to-line modes.
② And a semi-dry mud kneading stage. At this stage, after the dry powder is uniformly mixed, a binder liquid or solvent is added, and the raw materials are wetted and in a mud state. Through the powerful stirring of mixer, the material receives the shearing and the friction of mechanical force, also has the internal friction between the granule simultaneously, under each effort, tends to highly disperse between the raw materials granule. This stage has a crucial impact on the particle size and viscosity of the finished slurry.
③ And diluting and dispersing. After the kneading was completed, the solvent was slowly added to adjust the slurry viscosity and the solid content. At this stage, dispersion and agglomeration coexist, and finally stabilization is achieved.
