What are the reasons for the inability to disperse high-viscosity slurries? The mechanisms behind poor dispersion and design points for solutions.

Reproducibility of slurry dispersion is created from process design.

This is a solid-liquid mixing system designed to solve issues such as dispersion variability and agglomeration that arise in battery and electronic materials slurries, starting from process design. It optimizes dispersion, mixing, and supply as a single integrated system, achieving highly reproducible slurry production. It accommodates electrode slurries, high-viscosity slurries, and nanoparticle dispersions, enabling stable production through inline continuous processing. It supports consistent scale-up from research and development to mass production, balancing quality and productivity. If you are facing challenges with slurry dispersion, please feel free to consult us. We can also offer proposals for test verification and process design.

Verify before failing in mass production. Confirm the reproducibility of slurry dispersion in advance.

In the dispersion process of battery slurry, it is often observed that while dispersion can be achieved without issues during the research phase, it cannot be replicated during mass production, leading to quality problems. This is particularly true for positive and negative electrode slurries and CNT conductive materials, where variations in powder input conditions, dispersion energy, viscosity changes, and differences in process configuration can significantly alter the dispersion state and coating properties. Our service conducts dispersion tests at the lab scale based on the customer's materials and formulation conditions, evaluating the dispersion state, viscosity characteristics, and reproducibility. Furthermore, we support scale-up verification using small machines and pilot equipment, visualizing risks during mass production in advance. This is not just a simple test; through verification that delves into process design, we assist in reducing troubles during the transition to mass production and shortening the startup period.

CNT dispersion is determined by the process. Control of aggregation stabilizes conductivity.

In conductive paste using CNT (carbon nanotubes), the strength of aggregation and the difficulty of dispersion are challenges. If not sufficiently dispersed, a conductive network will not form, leading to unstable performance; on the other hand, excessive shear can lead to the destruction of the CNT structure, making the optimization of dispersion conditions essential. Furthermore, even slight differences in the dispersion state can significantly affect viscosity and conductivity, becoming a factor in quality variation during mass production. This system appropriately breaks down CNT aggregation while maintaining structure through process design that includes powder input, wetting processes, dispersion energy control, and circulation conditions. It is designed with the same logic from the lab to mass production, achieving a balance between conductivity and reproducibility.

Supports high-viscosity dispersion of positive and negative electrode slurries. Assists in quality stabilization and mass production scale-up through continuous processing.

This is an inline dispersion system designed for high solid content and high viscosity slurries used in battery materials. It achieves uniform dispersion through high shear dispersion for materials that are prone to aggregation, such as positive electrode materials, negative electrode materials, conductive materials, and CNT dispersions. The inline continuous processing reduces dispersion variability, improves quality reproducibility, and stabilizes production. Additionally, it supports process design that includes powder supply, dispersion, degassing, and transfer. By optimizing powder supply conditions, shear conditions, circulation conditions, and temperature control conditions, it helps stabilize slurry quality. It supports consistent scale-up from lab tests to pilot validation and mass production lines. It is utilized to address specific process challenges of battery material slurries, such as viscosity increase due to high solid content, sedimentation, agglomeration, and CNT aggregation. Furthermore, based on processing volume and material characteristics, it is also possible to propose systems that combine inline dispersers, batch-type dispersers, static mixers, and more.
