German mechanical and plant engineering firm Dürr has introduced its GigaCoater simultaneous two-sided coating technology for battery cell OEMs.

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.
