SOUTHFIELD, MI—Dürr has introduced a new iteration of its GigaCoater system for automated manufacturing of battery electrodes.
The system coats both sides of an electrode substrate simultaneously. It can accommodate substrate widths of up to 1,200 millimeters.
The GigaCoater features a straight-path product flow. This streamlined configuration results in a more compact footprint, reduces energy consumption, and eliminates edge curl after drying. The coating process uses a slot-die against a backing roll, followed by a tensioned-web-over-slot-die process, enabling simultaneous two-sided coating of the foil in a single pass. An air flotation dryer ensures even, noncontact drying on both sides, which improves electrode quality.
The simplified layout of the machine results in operational cost savings due to less energy consumption, reduced coil handling, fewer operating personnel and less material waste.
In addition to cost savings, the GigaCoater enhances product quality by eliminating edge curl, ensuring uniform drying on both sides, and improving top-to-bottom alignment.
With the GigaCoater,Dürrexpands its portfolio of simultaneous two-sided coating machines, which includes the PilotCoater and ProCoater. The PilotCoater can handle foils up to 350 millimeters wide with coating speeds of up to 10 meters per minute. The ProCoater accommodates web widths from 350 to 700 millimeters and coating speeds of up to 50 meters per minute.
