Battery Electrode Slitting Machine

Product Specifications

Technical details and manufacturing context for Battery Electrode Slitting Machine

Definition

A standalone industrial machine designed for high-precision slitting of battery electrode foils into required widths. It processes coated electrode materials (anodes and cathodes) by cutting them into precise strips for subsequent cell assembly. The machine ensures clean, burr-free edges to prevent internal short circuits and maintain electrode integrity. It is essential for lithium-ion, nickel-metal hydride, and other battery manufacturing processes where dimensional accuracy directly impacts battery performance and safety. The machine handles input foil widths from 600 to 1200 mm, producing slit strips as narrow as 10 to 20 mm, with a slitting accuracy of ±0.05 to ±0.1 mm. It operates at speeds up to 60 to 120 m/min, with tension control ranging from 10 to 200 N to maintain material stability. The unwind roll diameter can be up to 400 to 600 mm. The machine is constructed with stainless steel, tungsten carbide, and industrial ceramics for durability. Slitting blades are available in carbide or high-speed steel (HSS), with carbide recommended for abrasive coatings. The control system uses PLC and HMI for automated setup and monitoring. Power supply is three-phase, 380 to 480 V AC, 50/60 Hz, per IEC 60038. Operating temperature should be between 10 and 40 °C, and relative humidity should not exceed 85% to prevent foil sticking. The machine weighs between 2000 and 5000 kg, with a footprint of 3000×1500×1800 mm (L×W×H). These specifications are typical ranges; verify model-specific values with the manufacturer.

Working Principle

The machine uses precision rotary slitting knives or laser cutting heads to continuously slit wide electrode foil rolls into multiple narrower strips. Tension control systems maintain material stability during cutting, ensuring consistent strip width and edge quality. The process involves unwinding the master roll, guiding the web through the cutting station, and rewinding the slit strips onto separate cores. The control system monitors tension, speed, and alignment to achieve high accuracy.

Frequently Asked Questions

What materials can this slitting machine process?

It processes coated electrode foils for anodes and cathodes, typically aluminum and copper foils coated with active materials. The machine is designed for lithium-ion, nickel-metal hydride, and other battery types.

What is the typical slitting accuracy?

The slitting accuracy is ±0.05 to ±0.1 mm, depending on the model and material. This precision is critical to prevent edge defects that could cause short circuits.

What are the power requirements?

The machine requires a three-phase power supply of 380-480 V AC, 50/60 Hz, per IEC 60038. Confirm the exact voltage and frequency with the manufacturer for your facility.

How does the machine handle tension control?

It uses a tension control system that maintains web tension between 10 and 200 N during slitting. This ensures material stability and prevents stretching or wrinkling, which is essential for consistent strip quality.
