What Is a Laboratory Electrode Slitting Machine?
A laboratory electrode slitting machine is used to slit coated electrode coils (positive and negative) into multiple narrow strips of precise width. This process is critical for cell assembly – slitting quality directly affects battery internal resistance, consistency, and safety. Our unit is specifically built for research institutions and pilot lines, offering the same precision as production slitters but in a compact, flexible format.
Lab Slitter for Battery R&D – Key Features
This lab slitter for battery R&D includes the following advanced features:
Unwind unit – Automatic closed‑loop tension control ensures constant web tension, preventing stretching or wrinkling.
Industrial dust collector – Removes particles generated during slitting, keeping the electrode surface clean.
Rewind unit – Upper and lower slip‑shaft rewind with independent tension control, guaranteeing uniform roll hardness across all slit strips.
Unique slitting head design – Quick die changeover in less than 0.5 hour, minimizing downtime between different electrode widths.
Suitable for – Both anode and cathode electrodes (copper foil and aluminum foil) with typical thickness range 50–400μm.
