Subsecond dispersing of powders in lithium-ion battery slurries

YSTRAL Batt-TDS

Next Generation Technology

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.


OUR PROCESS

Pick a
Process

  • 1. Add solvent
    to vessel
  • 2. Dissolve binder
    @20-25°C
  • 3. Disperse
    carbon black
  • 4. Disperse
    additives
  • 5. Disperse
    active material
  • 6. circulate until
    homogeneous

Unprecedented flexibility. Materials are mixed under ideal conditions with each process challenge being addressed sequentially. Other technologies require ultra-high viscosities to achieve sufficient shear for dispersion unlike the Batt-TDS, which can generate it on demand.

Powder wetting directly into liquids. Unlike conventional mixing processes, which mix abrasive materials dry, the Batt-TDS employs the solvent as a lubricant, under a gentle process, and the metal contamination, caused by dry mixing, is eliminated.

In contrast to traditional processes, where binder is dissolved offline, our technology dissolves them at room temperature within 3 min of powder induction, independent of the batch size. With the Batt-TDS, dissolution can even be made in the same slurry sequence.

With the Batt-TDS, wetting and dispersion of aciniform structures can be optimized to disentangle agglomerates without particle destruction, ensuring the best conductive performance with any given formulation. Dry mixing / kneading is not required.

A wide variety of additives can be processed by the Batt-TDS. Whether powders, pastes or liquids, the Batt-TDS offers tremendous flexibility for process optimisation.

Induct and disperse active materials under vacuum at high viscosity and high solids content. Thixotropic (shear-thinning) slurries flow smoothly through the mixing chamber, allowing for efficient and continuous deaeration throughout the process.

Although dispersion only requires milliseconds, the batch is homogenised at low shear in the vessel, ensuring the lowest batch-to-batch variability. Electrode coating & SEM courtesy Dr. Werner Bauer and Dr. Marcus Müller, Karlsruhe Institute of Technology.

From Binder to Batt-TDS

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.

PRODUCT RANGE

Batt-TDS Navi

At R&D scale, the Batt-TDS navi can complete the entire slurry mixing process in just a few minutes, making it ideal for formulation and process screening, enabling faster R&D cycles for more robust product development.

Dispersion itself requires only milliseconds as components pass through its inline process chamber. The intuitive touchscreen HMI automatically captures mixing parameters for seamless scaleup.


Batt-TDS Pilot

Whether as an interim solution on the way to mass scale production or for factories with the highest operational flexibility requirements, there is a Batt-TDS solution.

The pilot’s capacity is in line with today’s production requirements.


Batt-TDS PRO

The Batt-TDS PRO offers 10x higher productivity than conventional technologies and twice those of available extruders. The PRO is available in multiple configurations to meet a factory’s specific requirements at any projected volume. Its compact design is ideal for nest configurations, which offer the highest productivity per square meter of factory space of any system currently available. The modular design of the PRO enables easy access for on-site maintenance and more complex service tasks to be accomplished outside of the Production area. Furthermore, skid assemblies minimize growing pains from factory reconfiguration due to continual expansion.


Our trial centre

ystral’s state-of-the-art trial facility is available for formulation and process evaluation. The navi is sufficiently compact that it resides in a floor-mounted fume hood for handling NMP in compliance with REACH Restriction 71. Sensitive powders at R&D scale are safely handled within our sealed glovebox and powder containment hopper isolation system.

Customers are invited to attend trials with their component materials either in person or remotely using our augmented reality platform.
