Positive electrode slurry solid-liquid mixing dispersion system

The quality of the positive electrode slurry is determined by the process, not the equipment. A dispersed design that takes mass production into account.

In the positive electrode slurry of lithium-ion batteries, the ability to uniformly disperse active materials, conductive agents, and binders affects the coating properties, electrode quality, and stability of battery performance. In actual production environments, issues such as clumping during powder addition, aggregation of conductive materials, poor mixing due to increased viscosity, and variations in dispersion between batches often arise. Even if there are no problems during the research phase, it is not uncommon for these issues to hinder reproducibility in mass production. This system designs the entire process of positive electrode slurry, including powder supply, input conditions, dispersion energy, circulation conditions, and formulation processes, to suppress dispersion inconsistencies and undispersed materials. By focusing on process design rather than just the equipment itself, it supports consistent scale-up and reproducibility from laboratory validation to mass production lines. It is also possible to consider conditions tailored to the positive electrode materials and formulation conditions.

basic information

This is a solid-liquid mixing and dispersion system for cathode slurries that integrates powder supply, premixing, high-shear dispersion, circulation homogenization, formulation, and cleaning. It optimizes the input sequence, shear force, residence time, and fluid design according to the particle size distribution of the cathode material, the cohesiveness of the conductive material, binder addition conditions, solid concentration, and viscosity changes. It supports inline continuous processing, circulation processing, and batch processing, allowing for configuration proposals based on processing volume and formulation. The design accommodates not only equipment selection including high-shear dispersion devices (such as IKA), but also powder supply equipment, piping, storage tanks, CIP, data logging, and integration with upper-level systems. Scale-up design is conducted with the same philosophy for lab machines, small machines, pilot systems, and mass production machines.
