- New wide-web coating system uses simultaneous 2-sided process to produce up to 3 GWhr of battery output annually
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, VP of technology and development. “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.
