Product Introduction
The Electric Battery Electrode Slitting Machine MRX-FT300 is a precision electrode processing system developed for longitudinal cutting of lithium-ion battery electrode sheets after coating, drying, and calendering. It converts processed electrode material into narrower strips according to the dimensional requirements of subsequent cell assembly, helping establish consistent electrode widths for downstream battery manufacturing operations.
The MRX-FT300 uses an upper-and-lower circular knife configuration for synchronized roller slitting. During operation, the two cutting wheels rotate at the same speed and work together to separate the electrode sheet along the required cutting lines. This configuration is designed to provide a stable cutting process while maintaining clean and consistent edges.
An adjustable feeding guide helps position the electrode material before it reaches the cutting section. This allows operators to establish a suitable feeding path according to the required strip width and electrode format. The engagement between the upper and lower knives can also be adjusted to accommodate different electrode processing conditions.
The machine is designed for battery electrode sheets with thicknesses from 80 to 300 μm and supports cutting widths from 20 to 300 mm. With an adjustable maximum slitting speed of 4 m/min, the MRX-FT300 provides practical processing flexibility for laboratory and small-scale battery electrode preparation.
To improve operating safety, the cutting area is equipped with a transparent protective cover that allows operators to observe the cutting mechanism while reducing direct exposure to the rotating knives. The open-style knife mounting structure also simplifies knife removal and replacement during equipment maintenance and process adjustment.
The MRX-FT300 is particularly suitable for battery research laboratories, pilot-scale electrode preparation, and cell development facilities where coated electrode materials need to be converted into accurately sized strips before winding, stacking, or other cell assembly operations.
