Single-piece Laser Notching & Cutting Machine

USE CASES

Cuts individual electrode sheets directly from coated foil using non-contact laser processing for flexible formats and rapid design validation.

 

Why this machine: Large-format electrodes with thick coatings are prone to edge deformation under mechanical stress. This non-contact laser system maintains dimensional stability and coating integrity without tool wear.

 

Ideal User: ESS and EV battery developers using thick coatings or large-format layouts.

 

When to choose: When processing large, thick, or mechanically sensitive electrodes where edge quality is critical for stacking alignment.

Equipment Features

These features enable precise single-sheet contour formation under controlled thermal input.

  • Optimized for single-tab and monolithic electrode structures
  • Non-contact laser processing ensures clean and uniform edges
  • Servo-controlled web transport for stable continuous cutting
  • High repeatability fixed-length feeding system
  • Compact modular design for pilot or mass production lines
  • Integrated fume extraction for clean downstream processes

Core Advantages: Single-Sheet Cutting Models vs. Multi-tabs Cutting Models

Single-Sheet Cutting

  • Process Alignment: Optimized for stacking processes, where individual electrode sheets are precisely layered to form cells. This direct compatibility makes it the preferred choice for manufacturers focused on stacked electrode designs from the outset.

Multi-Tabs Cutting

  • Process Versatility: Primarily suited for winding processes, where continuous electrode webs are wound into cylindrical or prismatic cells. A key advantage is its adaptability: when paired with a post-cutting machine, it can also be reconfigured to support stacking processes, making it a future-proof choice for manufacturers uncertain about their long-term process roadmap.
