YSTRAL - Model Batt-TDS - Fast Lithium-Ion Electrode Slurry Mixing

SHARE
The YSTRAL Batt-TDS™ is a state-of-the-art technological innovation designed to revolutionize the mixing and dispersion process for lithium-ion battery slurries. This system operates by integrating powders into a liquid stream in a dust-free environment under vacuum, ensuring precise and optimal dispersion of components. It offers independent control of critical parameters like flow and shear rates, thereby providing a versatile solution adaptable to diverse material properties and topologies. The Batt-TDS™ technology allows for the production of high-solids slurries at high viscosities, significantly improving product quality and reducing processing time compared to conventional methods. The system is designed for scalability, making it a viable solution for both current industrial needs and future gigafactory demands. Unlike traditional methods that require ultra-high viscosities and offline binder dissolution, the Batt-TDS™ performs dissolution within three minutes of powder induction at room temperature. This innovative process prevents metal contamination and optimizes the dispersion of complex structures, ensuring superior conductive performance. The system can handle a wide range of materials including powders, pastes, and liquids, offering unparalleled flexibility. Its thixotropic slurry management ensures smooth flow and continuous deaeration, maintaining low batch-to-batch variability. With its compact design and high productivity per square meter, the Batt-TDS™ minimizes production costs and space requirements, making it an efficient and cost-effective solution for battery slurry production.

The Batt-TDS™ inducts powders dust-free under vacuum into a stream of liquid, thereby creating conditions for optimal dispersion of diverse components in a continuous sequence. Independent control of key parameters, including flow and shear rates, offers a wide process window in a single piece of equipment.

A ‘swiss-army knife’ of process tools for battery slurry
Dispersion of diverse materials is tailored according to their specific physical properties and topologies with the capability to produce high-solids slurries at high viscosities.

Scalable and cost-efficient
The Batt-TDS achieves high product quality in a fraction of the time required by conventional processes. Easily scalable across various battery chemistries, the Batt-TDS solution is suitable for production at current industrial levels and ready for tomorrow’s gigafactories. The platform offers a low cost of ownership with the highest productivity per square meter of factory space.

ystral has been the leading company for dispersion and dissolution processes for numerous individual components such as PVDF, CMC, carbon black and graphite across multiple industries for more than 20 years. ystral solutions can be incorporated to enhance your existing processes such as reducing binder or conductive paste preparation time, improving quality, lowering energy costs and minimising equipment footprints.

With the surge in demand for lithium-ion batteries, ystral set out to develop something special for the industry. The ystral development team did not conclude by merely mastering each process in an application development activity, but instead leveraged its extensive experience to build all required functions into a single platform for slurry production.
