Slitting machines are tools within energy research designed to process rolls of electrode (anode and cathode) material into precisely cut, narrower widths and specific shapes, to fit different types of batteries (e.g. pouch, cylinder).
A slitting machine cuts wide rolls of flexible materials into specific-sized strips, then rewinds them onto smaller rolls. This is essential for industries needing specific material widths for downstream processing or end-use.
The precision, speed, and versatility of slitting machines are paramount in sectors demanding high-quality, precisely-sized material rolls, facilitating subsequent manufacturing processes and contributing significantly to product integrity and performance.
Whether you're working with films, foils, laminates, or electrode materials, slitting machinery ensures accuracy and repeatability, making it ideal for both production and pilot-scale research.
A typical larger slitting machine consists of three key components:
• Unwind unit - feeds the master roll into the machine, incorporating tension control systems and edge guiding to ensure precise alignment
• Slitting unit - equipped with blades or rotary cutters that divide the material to your specified widths
• Rewind unit - collects the slit material into smaller, uniform rolls, utilising various winding shafts
Smaller, manual slitting machines are available to cut singular electrode sheets.

Key Features & Options
Functionality: Manual, pneumatic, semi-automatic or fully automated versions available
Slitting Width: Adjustable, scaling from 3-10 mm width model for micro-batteries, to maximum 750 mm for cylinder/pouch cells
Slitting Section: The core cutting area, employing various methods:
Shear Slitting: Two circular blades act like scissors for clean cuts (e.g., paper, film, foil).
Razor Slitting: A fixed or oscillating razor blade for thin, delicate films.
Crush Slitting: A blade presses material against an anvil for materials like pressure-sensitive adhesives. Precise blade positioning is crucial, often automated. Slitting speed/blade materials/thickness.
