B&W MEGTEC Introduces the GigaCoater™ for Lithium-Ion Battery Electrodes

New wide-web coating system uses simultaneous 2-sided process to produce up to 3 GWhr of battery electrode output annually, creating enough capacity for 30,000 electric vehicles configured for 100 kWh or 5 hours of backup power for 300,000 homes based on average consumption of 2 kWh.

B&W MEGTEC Introduces the GigaCoater™ for Lithium-Ion Battery Electrodes


New wide-web coating system uses simultaneous 2-sided process to produce up to 3 GWhr of battery electrode output annually

(De Pere, Wis. - Sept. 12, 2017) Babcock & Wilcox MEGTEC (B&W MEGTEC), a subsidiary of Babcock & Wilcox Enterprises, Inc., has launched the GigaCoater™ wide-web coating line for lithium-ion battery electrodes.

Developed to provide high-volume production of battery electrodes, each GigaCoater can produce up to 3 GWhr of electrode per year on average. The GigaCoater coating platform utilizes B&W MEGTEC's exclusive simultaneous 2-sided coating system.

"The energy storage industry is demanding a significant reduction in production costs in combination with increased yields and product quality," said Jeff Quass, vice president of technology and development, B&W MEGTEC. "The GigaCoater offers increased foil width and faster speeds. Coupled with our simultaneous two-sided coating system, the GigaCoater provides a simplified coating line that approximately doubles manufacturing capacity within the same footprint as a single-side sequential line."

The dual-coating method, in combination with coating rheology and GigaCoater machine properties, maximizes production time and delivers in-line quality control. Additional GigaCoater specifications include:

• Web width of 1,300 mm
• Coating width of 1,200 mm
• Mechanical speed of 50/m/min
• Process speed of 40 m/min
• Wet coat weight of up to 400 gsm/side

"Manufacturing large quantities of lithium-ion battery cells requires a significant change and dimensional up-scaling of the production equipment and output per line to achieve industry targets," Quass notes. "At the same time, the benefits of two-sided simultaneous coating technology become increasingly important the wider and faster coating lines are required to get."

The GigaCoater maximizes manufacturing at a significantly lower total production cost with:

• 50 percent to 70 percent less floor space than typical single-side coating operations, which allows for more efficient plant layouts
• Thermal efficiencies that deliver lower energy requirements
• A wide-web width that significantly reduces the number of coils needing to be handled
• Simplified material flow that enhances overall throughput
• Higher automation that maximizes production volume

SCHUNK's New Safety Gripping System EGN

SCHUNK's New Safety Gripping System EGN

With the SLS, SOS, and STO functionalities, the SCHUNK EGN gripping system certified in accordance with DIN EN ISO 13849 enables safe human/machine collaboration. If the production process is interrupted by an emergency shut-off, the SCHUNK EGN goes into either a safely limited speed mode or a safe stop mode depending on the activated protection zone. In contrast to other solutions available on the market, the SCHUNK safety gripping system is continuously powered even in the safe operating stop so that the gripped parts are reliably held even without mechanical maintenance of gripping force. As soon as the protection zone is released, the gripper immediately switches back to the regular operating mode without the system having to be restarted.
