Electrode Punching Machine

Electrode Punching Machine – Lithium Ion Battery Electrode Die-Cutter for Glove Box

The Electrode Punching Machine is a precision die-cutting equipment designed specifically for cathode and anode electrodes used in lithium-ion batteries manufactured through the stacking process. Utilizing pneumatic operation, this machine delivers consistent, high-quality electrode sheets for research laboratories and small-scale production environments.

Working Principle:

Sheet electrodes are manually fed into the machine. The pneumatic system drives the upper die downward against the lower die, cutting the electrode material into the desired shape using a knife template. The cutting force and speed are adjustable to accommodate different electrode materials and thicknesses. The drawer-style design ensures safe and easy die changes.

Key Features:

• Pneumatic Operation: Reliable and adjustable cutting force up to 1 Ton (1 MPa) .
• High Precision: Cutting accuracy of ±0.1 mm with minimal burr formation (vertical ≤12μm, horizontal ≤20μm).
• Standard Dies Included: Comes with cathode (56×43mm) and anode (58×45mm) cutting dies.
• Large Cutting Area: Max die-cutting size L120 × W80 mm (including battery tabs).
• Customizable Dies: Various shapes and sizes available according to customer requirements.
• Glove Box Compatible: Compact design suitable for use inside argon-filled glove boxes.
• Adjustable Parameters: Cutting force and speed can be tuned for optimal results.
• Durable Construction: High-strength frame, precision upper/lower pressure plates, and high-performance cutting tools ensure long-term accuracy.
• Safe Operation: Drawer-style upper and lower blade die design prevents accidental contact.
• Long Die Life: Cutting die lifespan of 10,000 cycles for reliable production.

Applications:

• Die-cutting cathode and anode electrodes for lithium-ion stacking process batteries
• Laboratory-scale electrode preparation
• Small-batch production of battery electrodes
• R&D of new electrode designs and materials
