An electrode slurry refers to a mixture of active material, conductive additives, solvents and binders. Battery processors apply this mixture onto copper and aluminum foil, followed by drying and calendaring, to form the cathode and anode in the battery cell. Battery electrode slurry preparation is essential in battery manufacturing for poor battery slurry mixing can lead to inefficient electron conduction. Then it would result in non-uniform battery reactions.
Battery electrode slurry mixing is important for the sedimentation stability of the slurry. The battery slurry viscosity indicates the dispersion efficiency of the components. In other words, viscosity has a direct influence on leveling and wet-layer thickness for coating process. Precise lithium ion battery slurry viscosity measurement and control means a lot for battery producers. Explore Lonnmeter viscometer collection and find more professional product solutions here.

Understanding Effective Slurry Mixing and Coating
Slurry mixing and coating determine battery performance and quality to a great extent, particularly for lithium-ion batteries. It’s a process of preparing a homogeneous suspension and applying it to copper and aluminum foil. Battery slurries are a complex suspension containing large content of solid particles in a viscous media. A thorough slurry mixing for battery guarantees homogeneity of battery slurries while rheological properties affect slurry stability, ease of mixing and coating performance.
Density and viscosity define the flow characteristics of a material, reflecting its internal structure and determining whether it exhibits solid-like or liquid-like behavior. In electrode manufacturing, the viscosity of in-process materials is crucial, significantly impacting battery fabrication processes like coating. The viscosity of the polymeric binder solution directly impacts coating performance, influencing how easily powders disperse, the energy needed for mixing, and the speed of applying a uniform coating.
Process Challenges in Battery Slurry Mixing and Coating
Real-time monitoring and controlling over electrode slurry guarantee density and viscosity parameters falling in reasonable range, making sure stable density and viscosity level.
1. Unexpected agitation disrupts internal structures with time in the mixing process.
2. Over-viscous slurry results in poor dispersibility and low film uniformity.
3. Highly viscous battery slurry increases resistance to sedimentation and thickness of electrode film.
4. Inappropriate density results in irreversible capacity loss in lithium-ion batteries.
