In the manufacturing process of lithium batteries, slurry preparation is a crucial step. The quality of the slurry directly affects the electrochemical performance, production efficiency, and safety of the battery. In actual battery mixing machine production, problems such as slurry settling and large viscosity changes often occur, which affect the consistency of batteries. Analyzing the causes of these problems and finding effective solutions are of great significance for improving the production efficiency and stability of lithium batteries.   1、 Cause analysis 1). Unstable water absorption of slurry: The water absorption of slurry is an important factor affecting its stability. When the slurry absorbs too much water, it can cause changes in its composition, thereby affecting its physical properties such as viscosity. In addition, water absorption can also cause the solid particles in the slurry to condense, thereby accelerating the sedimentation of the slurry. 2). Insufficient adhesive: Adhesive is an important component in maintaining the stability of the slurry. If the adhesive content is insufficient, the viscosity of the slurry will decrease, leading to poor stability and easy sedimentation. 3). Poor dispersion effect: During the preparation process, if solid particles cannot be fully dispersed in the medium, it will lead to poor dispersion effect of the slurry, which will affect its stability. The agglomeration and sedimentation of solid particles can lead to inconsistent battery performance and may even cause safety issues for the battery.   2、 Solution 1). Adjust the selection of raw materials The selection of raw materials has a crucial impact on the stability of the slurry. Choosing appropriate raw materials, such as fillers and binders with lower water absorption, can effectively improve the stability of the slurry. In addition, optimizing the particle size and specific surface area of raw materials can also improve the dispersion and viscosity of the slurry.      2). Adjust the mixing process The stirring process is one of the key factors affecting the stability of the slurry. Optimizing the mixing process can improve the dispersion effect of solid particles in the slurry and reduce the settling speed. Specific measures include adjusting parameters such as the speed, linear speed, and mixing time of the mixer. An appropriate stirring process can evenly distribute solid particles in the slurry, thereby improving the stability of the slurry. 3). Adjust the amount of adhesive used Adhesive is an important component in maintaining the stability of the slurry. By adjusting the amount of binder, the viscosity and stability of the slurry can be optimized. While ensuring that the binder can fully encapsulate solid particles, avoid excessive addition that may cause the slurry to become too thick. Determining the optimal amount of binder through experiments can effectively solve the problem of large vis...
