Stability Analysis of Electrode Slurries based on Static Multiple Light Scattering
The rapid growth of the new energy industry has increased the demand for high-performance batteries. Conventional batteries, such as lithium iron phosphate and ternary lithium batteries, are produced using electrode slurries, where the positive or negative active material is typically mixed with binders, additives, and solvents. Electrode slurries that are unstable may result in undesirable phenomena such as flocculation and sedimentation of active material particles, severely impacting the subsequent coating and calendering processes, as well as the overall battery performance. The stability of electrode slurry is affected by factors such as the composition and percentage of ingredients, the particle size and size distribution of the active material particles, the viscosity of the medium, and the mixing processes. An optimal formula can ensure the mechanical and conductive properties of the electrode slurry.
