German mechanical and plant engineering firm Dürr has introduced its GigaCoater simultaneous two-sided coating technology for battery cell OEMs. slot die coating head
GigaCoater combines wider substrate capabilities with faster coating speeds, which has the potential to reduce manufacturing costs while maintaining automotive-grade quality across widths up to 1,200 mm.
The machine features a straight-path product flow with two coating stations combined in a single location, complemented by a non-contact flotation drying system. This streamlined configuration results in a compact manufacturing footprint, reduces energy consumption and eliminates edge curl after drying, according to the company. The coating process uses a slot-die against a backing roll, followed by a tensioned-web-over-slot-die (TWOSD), enabling simultaneous two-sided coating of the foil in a single pass. The air flotation dryer ensures even, non-contact drying on both sides, further improving electrode quality.
The GigaCoater expands Dürr’s portfolio of simultaneous two-sided coating machines, which previously consisted of the PilotCoater and ProCoater.
