Against the backdrop of accelerated iteration of EV lithium battery manufacturing processes toward higher precision and greater flexibility, traditional mechanical die cutting is plagued by severe die wear, lengthy model changeover cycles and insufficient process flexibility, rendering it unable to meet the industry’s development goals of quality improvement and cost reduction. As a new-generation core process, laser tab forming has become a pivotal path for upgrading electrode manufacturing. Lyric’s self-developed vertical integrated laser notching and slitting machine delivers technological breakthroughs in three core dimensions: underlying algorithms, full-process closed-loop control and structural innovation, creating an intelligent, highly flexible all-in-one equipment for increasing production and efficiency.

Superior Core Performance Underpins High Productivity

Centered on intelligent algorithms and full-link closed-loop control, the machine achieves dual breakthroughs in high processing speed and ultra-high precision. Equipped with self-developed underlying cutting algorithms, it customizes cutting trajectories based on tab geometries and electrode substrate materials, enabling dynamic matching of laser power and frequency. It supports special-shaped processing including gradient tabs and laminated V-notches, breaking the customization limitations of conventional single-trajectory algorithms.

Furthermore, the machine adopts a full-process closed-loop management system integrated with CCD visual position correction and high-speed multi-axis tension control. Tension fluctuation under constant running speed is controlled within ±3 N, cutting accuracy remains steady at ±0.2 mm, and electrode sheet jitter is suppressed to within ±0.3 mm. The stable production speed ranges from 80 to 120 m/min, with a peak cutting speed of 180 m/min. Its throughput is 2 to 3 times higher than that of traditional mechanical die-cutting equipment. The burr height of anode electrodes is ≤15 μm, and the heat-affected zone (HAZ) of cathode electrodes is ≤70 μm, which fully guarantees consistent tab processing performance and cell safety.

Technological Breakthroughs Address Universal Industry Challenges

Targeting two widespread industry pain points — electrode jitter during high-speed cutting and dust accumulation — the machine adopts an innovative side-suction composite cutting chamber. This structural design fundamentally suppresses tab vibration at high line speeds, while supporting backboard cutting mode. Mode switching takes merely 20 minutes to accommodate diverse process requirements.

A composite dust removal system delivers ultra-clean manufacturing, maintaining an ISO 7 (Class 10,000) cleanliness class inside the machine cavity. No obvious dust buildup occurs within the chamber after 24 hours of continuous operation, and surface particles on electrodes are controlled below 10 μm. Paired with an electric cylinder compacting waste collection system, the unit drastically cuts maintenance frequency and ensures long-term stable operation of the production line.

The machine delivers full-process flexible coverage, supporting 1-up and 2-up processing modes. It integrates tab forming and electrode slitting in one single pass, compatible with multiple battery formats including prismatic, pouch and cylindrical cells. It accommodates incoming web widths ranging from 100 mm to 600 mm, satisfying flexible production requirements for prototype lines and small-to-medium mass production lines. Product changeover is completed merely via program switching, overhauling the inefficient conventional die-cutting model that requires full die replacement for every product switch.

Process integration eliminates the pre-slitting step, bringing a 32% reduction in equipment footprint, 50% cut in labor costs, 40% higher material turnover rate and 10% improvement in foil utilization rate. Meanwhile, it completely eradicates die wear and recurring die maintenance costs associated with traditional mechanical cutting tools, slashing manufacturers’ long-term operational expenditures across all dimensions.

With outstanding performance and reliable stability, Lyric's vertical laser die-cutting and slitting integrated machine has earned long-term recognition from multiple leading companies in the industry. Looking ahead, Lyric will continue to deepen its expertise in laser processing technology, steadily advancing the intelligent and high-end upgrading of lithium battery equipment, and injecting strong momentum into the high-quality development of the global new energy industry.
