This high-precision multi-tabs laser notching and slitting machine for lithium-ion and sodium-ion battery electrodes delivers burr-free cuts (10-15μm) and slitting accuracy (±0.3 mm). Its core value lies in enabling superior current distribution for high-power drone and wearable pouch/prismatic cells, by achieving flawless tab geometry that minimizes internal resistance and heat generation, which is critical for fast-charging and safety.
Performs simultaneous tab shaping and web slitting of coated electrode rolls to create precise multi-tab geometries required for high-current pouch and prismatic cells.
Why this machine: Multi-tab designs improve current distribution but are sensitive to burrs. Laser processing ensures clean edges and precise geometry that mechanical die-cutting cannot match, reducing internal resistance and heat.
Battery developers focused on 100W+ fast-charging technologies for EVs and high-end flagships, where multi-tab design is essential for heat dissipation and minimizing internal resistance.
When using multi-tab architectures where tab accuracy directly impacts thermal distribution and safety.

This section outlines where the Multi-tabs Laser Cutting & Slitting Machine is positioned within the electrode manufacturing workflow.
At this stage, coated electrode rolls are converted into multi-tabbed sheets and slit to defined widths for downstream cell assembly.
Packaging focuses on protecting laser optical modules, slitting units, and motion alignment references.
This equipment is based on the patented
“Integrated Die-Cutting and Slitting Machine for Multi-Tab Electrode Processing.”
The design utilizes a synchronized dual-die structure to perform tab forming and width slitting within a single mechanical cycle, eliminating secondary alignment steps required in conventional processing.
This integrated approach removes sequential handling steps, reducing maintenance and improves positional consistency while sustaining the high-throughput production required for multi-tab electrode manufacturing.
Certification scope and compliance documentation for this equipment are provided in the dedicated Certifications & Compliance section.
Multi-tab electrode architectures are increasingly used to reduce current density and improve thermal distribution in high-power pouch cells. However, they impose extremely strict requirements on tab geometry, edge quality, and positional accuracy.
This laser-based system eliminates mechanical stress and burr formation commonly seen in die-cutting, ensuring uniform tab dimensions and clean edges. The result is lower internal resistance, improved heat dissipation, and higher long-term cell stability in fast-charge and high-rate applications.
