Market Trends

Copper and Aluminum Welding with Green and Blue Lasers

The adoption of green and blue wavelength lasers is accelerating because of higher absorption rates in copper and aluminum. This has led to fewer spatter defects, deeper penetration, and more reliable production of busbars and interconnects. Multi-kilowatt visible lasers are increasingly standard in 2025 production lines.

Real-Time Weld Quality Monitoring

Inline sensing is becoming mandatory. Systems now include closed-loop controls that monitor weld geometry and depth in real time. Manufacturers report significant reductions in destructive testing and faster line ramp-up. By 2026, inline monitoring is expected to be standard in nearly all new gigafactory installations.

Electrode Notching as a Bottleneck Breaker

Notching is a speed-limiting process. Hymson's high-speed notching machines have raised electrode line capacity dramatically. With global demand for higher cell throughput, electrode processing investments are a major focus in 2025.

Adoption for New Battery Formats

The transition to 46-series cylindrical cells and high-nickel or LFP chemistries requires more precise welding of can caps and interconnects. Laser welding is outperforming ultrasonic methods in speed and quality, making it the dominant joining method for these new designs.

Growth in Energy Storage Systems

Grid-scale energy storage projects are expanding rapidly in 2025. Demand for prismatic and pouch module welding is rising, especially in large-scale renewable integration. This segment is creating additional demand for enclosure sealing and precision welding.

Recycling and De-Manufacturing with Lasers

Laser-based processes for de-coating, selective delamination, and safe pack opening are emerging as cost-effective methods for battery recycling. This is a new revenue stream for equipment suppliers beginning in 2025, driven by the first wave of returned EV batteries.

Predictive Maintenance and Smart Factories

Manufacturers are prioritizing equipment with predictive maintenance features and integrated monitoring. Wuxi Lead's systems show significant cost savings, and similar offerings are being introduced by other global suppliers.

Busbar Welding Competitiveness

Laser welding continues to displace ultrasonic welding in busbar connections due to higher throughput, flexibility across materials, and fewer joint defects. Dual-beam and ring-mode lasers are gaining ground as mainstream solutions.

Strategic Outlook 2025-2031

The lithium-ion battery laser system market will more than double in size by 2031. While tariff policies and global supply-chain risks introduce uncertainties, adoption of high-power visible lasers, inline quality assurance, and recycling applications will define growth trajectories. Equipment makers that integrate automation, monitoring, and flexible process capabilities are positioned to gain market share as the industry transitions to larger gigafactories and diversified battery formats.
