Solid-liquid mixing dispersion system for LiB (lithium-ion battery materials)

The quality of the battery slurry is determined by the process. A dispersion design that can be reproduced from research to mass production.

In the manufacturing of lithium-ion batteries (LiB), the dispersion quality of the positive and negative electrode slurries and conductive material pastes significantly affects battery performance, lifespan, and safety. On-site challenges include clumping during powder input, agglomeration of conductive materials, poor mixing due to increased viscosity, and variability between batches. Particularly in the research phase, issues may not arise, but many cases are observed where they cannot be replicated during mass production. Many of these challenges stem not from individual equipment but from the entire process, including input conditions, dispersion energy, fluid design, and process configuration. This system is designed to provide a consistent approach from powder supply to dispersion and formulation, establishing an optimal dispersion process tailored to material properties and formulation conditions. By designing with the same logic from the lab to small machines, pilot, and mass production lines, reproducibility and quality stability during scale-up are achieved. It is also capable of accommodating process design according to the characteristics of the positive electrode, negative electrode, and conductive materials.

basic information

A solid-liquid mixing and dispersion system that integrates powder supply, premixing, dispersion, circulation homogenization, formulation, and cleaning. We conduct process design considering particle size distribution, specific surface area, concentration, and viscosity changes according to the characteristics of positive electrode materials (NCM, LFP), negative electrode materials (graphite, Si-based), and conductive materials (CNTs, etc.). By optimizing the order of input, shear force, residence time, and fluid design, we suppress agglomeration and achieve uniform dispersion. The system supports inline continuous processing, circulation processing, and batch processing, allowing for configuration proposals based on processing volume and application. In addition to selecting equipment including high-shear dispersion devices (such as IKA), we also accommodate powder supply equipment, piping design, storage tanks, CIP, data logging, and integration with upper-level systems. We provide consistent scale-up design from laboratory machines to mass production lines.
