Accelerating lithium-ion battery development & production
29 June 2021
In response to an unprecedented surge in demand for lithium-ion batteries, driven by soaring sales of electric vehicles (EVs) & impacting the need for large-scale battery manufacturing, ystral has launched its Batt-TDS™ series of powder dispersing systems for development & industrial production of electrode slurries for lithium-ion batteries. The platform offers crucial benefits, compared to existing technologies.
Thanks to substantial process advances, ystral can provide battery manufacturers with a solution that is characterised by its high-speed process. The Batt-TDS has the flexibility to handle diverse materials by combining multiple functions of several machines into a single core system.
At R&D scale, compared to planetary mixers, which require hours of mixing to accomplish dispersion, the Batt-TDS can complete the entire process in a few minutes, enabling faster R&D cycles for more robust development. Dispersion itself requires only milliseconds, as components pass through its inline process chamber.
At production scale, this translates to greater than 10x higher productivity than conventional technologies and twice that of available extruders. Easily scalable across various battery chemistries, the Batt-TDS solution is suitable for production at current industrial levels and ready for tomorrow’s gigafactories.
Next generation process technology
ystral’s 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. With independent control of each key parameter, the new technology offers a wide process window in a single piece of equipment. This cannot be achieved with existing systems such as a high-speed dissolver, planetary mixer or even the more modern extruder. Dispersion of polymeric binders, conductive carbons and abrasive active materials is tailored according to their specific physical properties and topologies. The unique technology is able to process high-solids slurries at viscosities exceeding industry requirements, and the wash-in-place (WIP) feature maximises machine availability
Scalable & cost-efficient
The product range includes a 12-litre unit for rapid formulation and process screening, as well as production systems for a throughput greater than 5,000 litres per hour. David Manke, CTO & Managing Director at ystral said: “The Batt-TDS is the veritable ‘swiss-army knife’ of process tools for battery slurry. We can now present manufacturers worldwide with a technology to achieve high product quality in a fraction of the time required by conventional processes.” Richard Potter, Director of ystral Asia added: “The platform offers a low cost of ownership with the highest productivity per square meter of factory space.”
