Perforating copper foil at line speed
A perforation pattern cut in the web at line speed, with no tooling to wear. Coated-electrode results are established per chemistry in the trial.
Industry
LasX develops laser processing for battery and energy applications — coated electrode foils, fuel-cell gaskets and membranes, and cell packaging materials — where mechanical cutting leaves burrs and particulate that a cell cannot tolerate.

Applications

A perforation pattern cut in the web at line speed, with no tooling to wear. Coated-electrode results are established per chemistry in the trial.
Several LaserSharp® modules cut and perforate a wide metal-foil web at line speed — the approach for electrode foils and current collectors, where die wear and burr control are the problem.

A selective ablation window in coated graphite energy material, from application development. Ultrashort pulses keep the heat-affected zone down.
Fuel-cell components cut without the burrs and particulate that mechanical cutting leaves. Burr height and heat-affected zone are measured in the trial.
FoilPro™ runs coated and bare foil roll-to-roll, with LaserSharp® modules on NIR and green sources, nanosecond through femtosecond, and the tension control, splice handling and extraction a metal web needs. No tool-wear drift to manage across a run. We measure burr height in the trial. The parameters are proven on your chemistry in the lab before anyone quotes a machine.
Contract processing of electrode materials, fuel-cell components, and battery package structures — development quantities through pilot production.
Every mechanical process that touches an electrode wears, and wear drifts. A cell maker's cut-quality problem is usually a consistency problem — which is exactly the failure mode a digital process removes.
Measured, not assumed. We characterize debris generation and edge quality per material and parameter set in the lab, then design the extraction to that result. For cell materials the data is the deliverable that matters.
Trials in the PhotonX lab come back as processed samples and a written report — not a proposal.
