1] Precision Die Cutter for Pouch Cell Electrode Sheet:
Description:
It is a precision electrode die-cutting machine. It is a must-have tool for
producing specific shapes of positive and negative electrodes with current collectors in
pouch cell production lines. An IR sensor (safety curtain) built into the front of the machine
ensures safe handling when the electrode pads are fed from the front.
It is a necessary tool in the production line of Li-ion pouch cell battery to produce specific shapes of cathodes and anodes with current collector tabs. The size of the electrodes it cuts perfectly matches the standard pouches made by the cup forming machine, and the shape of the electrodes it produces is also handy for the latter processing steps of tab welding and electrode stacking.
