Li-Ion Battery Electrode Manufacturing
Dürr provides a comprehensive turnkey solution for producing coated materials for battery electrodes. Our capabilities cover both ends of the production line, as well as everything in between. We provide systems for raw material handling, slurry mixing and fluid delivery, web handling, coating and drying, solvent recovery and purification, calendering, and slitting.
Li-ion battery electrode manufacturing benefits
By complementing our own technology with that of world-class partners, Dürr can offer a turnkey battery electrode plant. Our manufacturing solutions for optimizing battery electrode production include simultaneous two-sided coating made possible by the Dürr tensioned-web coating system.
Process overview
Dürr’s simultaneous two-sided coating systems provide many benefits. Our solution for a complete electrode plant increases these benefits by applying them to all the steps in the process:
- Powder handling
- Slurry mixing
- Coating and drying
- Calendering/roll pressing
- Secondary drying
- Slitting
- NMP recovery and purification
Improved quality
Two-sided coating coupled with flotation drying offers:
- Improved side A to side B alignment
- No edge curl after drying
- Drying consistency for improved yield
- Reduced wrinkles due to flotation drying
Integrated solvent recovery and refining:
- Collects the NMP with condensation to minimize contamination
- Purifies on site to the highest standard of quality
- Closes the loop for solvent recycling
Lower total costs
The simplified process design requires lower capital investment. In addition, simultaneous two-sided coating with inline calendering/roll pressing reduces operating costs:
- Heating only one dryer
- Fewer operators
- Less material waste
- Increased yield
Integrated solvent recovery and refining:
- Includes heat recovery to reduce demand for utilities
- Minimizes waste
- Provides cost savings by capturing >99% of NMP
Ask us to prepare a cost model for your operation.
Simplified factory layout/material flow
With a straight-path product flow and single-level machine:
- The factory layout can be linear
- Direct slurry piping to a single coating station
- Reduced floor space for the coating area
Process development
During the machine build period, Dürr provides customer-specific process development trials, making it possible to dramatically reduce the period between commissioning and full production.
