Battery, PV & Energy Material Processing
Laser processing and inline inspection for battery electrode, PV thin-film, and energy-material manufacturing — pilot to giga-factory scale.
Step 1 — Define your goal
What are you trying to achieve?
Pick the experiment / project closest to yours. We'll route you to the right system architecture and BOM.
Step 2 — Confirm the problem
Common project challenges
If any of these sound familiar, you're in the right place. WaveQuanta engineers have seen — and solved — every one of them.
Thermal effect on coating layers
Even ns lasers cause coating delamination if heat builds up.
Processing efficiency at giga-factory volume
Cells / minute throughput requires careful pulse-rate / scan-speed tuning.
Edge quality on Cu / Al foil
Sub-µm burr for clean cell assembly without short circuits.
Thin-film damage control
Scribing P2 / P3 cleanly without damaging underlying or covering layers.
Inline coating-thickness inspection
Optical reflectance for real-time control.
Power stability over 24/7 operation
<1% pulse-energy drift over a 24-hour shift.
Process window stability
Consistent results across material lot variation.
Recipe portability between sites
Process must transfer to multiple production sites without re-tuning.
Step 3 — Understand the system
Typical system architecture
Most projects in this area follow a similar signal flow. Your specific architecture depends on resolution, throughput, and form-factor targets.
Fiber, fs, or ps source matched to material — 1030 / 515 / 1064 nm at 200–2000 W.
Power control, polarization, beam expansion before the focusing optics.
Pulse-by-pulse + average-power monitoring for closed-loop stability.
Thickness, defect, and edge-quality verification on the work line.
Reflectance spectroscopy for coating thickness; PL for material defects.

Step 9 — Common questions
Frequently asked questions
Quick answers to the questions our application engineers hear most often.
Battery foil cutting — fiber laser or fs?
Fiber laser (1064 nm): high throughput, low cost, edge burr ~3–5 µm, sufficient for most cell types. Fs / ps: sub-µm burr, premium for high-end cells, > 5× cost. Most giga-factories run fiber + post-process.
PV scribing — what's the throughput target?
For thin-film PV (CdTe, CIGS, perovskite): 1–5 panels/min for full P1/P2/P3 scribing. Polygon scanners + multi-spot strategies push this to 10+ panels/min.
How to handle thermal accumulation?
Three strategies: (1) burst-mode pulse trains with pause; (2) closed-loop power control with real-time thermal feedback; (3) cooled substrate fixturing. Engineering Validation tier ships with all three.
Inline thickness inspection — how accurate?
Reflectance spectroscopy: ±1 nm on metal foils, ±5 nm on dielectric coatings. White-light interferometry for <0.5 nm precision (slower).
Recipe portability between sites?
Engineering Validation tier ships with documented process recipe + reference samples + per-site calibration protocol. Recipe portability validated by WaveQuanta application engineer at each site.
Power stability over 24h?
Sealed industrial fiber lasers achieve ±1% pulse-energy drift over 24 hours when paired with closed-loop AOM attenuation and thermal-controlled enclosure.
Long-term supply for giga-factory?
WaveQuanta partners with giga-factory operators on 5–10 year supply contracts, with batch consistency reports, engineering change control, and end-of-life buyout.
Can WaveQuanta provide the full process recipe?
For Engineering Validation tier and above, yes — we run qualification on your specific material samples and deliver documented recipe (laser settings, scan strategy, focal trajectory, inspection setpoints).
