Product Summary
The Battery Pole Piece Slitter is an indispensable piece of Precision Instrumentation in the New Energy Research and battery manufacturing chain. Its function is to take large, master rolls of coated and calendered battery electrode material and precisely cut them into the narrow, uniform strips (pole pieces) required for final cell assembly (winding for cylindrical/prismatic cells or stacking for pouch cells).
The extreme accuracy of this process is paramount. Any deviation in width or the presence of rough edges (burrs) can lead to misalignment in the cell core or, more dangerously, penetrate the separator and cause an internal short-circuit, severely compromising cell safety and cycle life. This machine provides the necessary high-precision, clean-cut, and uniform tension essential for high-performance battery production.
Primary Applications
New Energy Research:
Electrode Preparation: A crucial, final step in electrode processing before cell assembly. The machine determines the exact width of the final electrode pieces that will form the core of the battery.
R&D and Pilot Line: Used to quickly produce small batches of various width electrodes for testing different cell formats and optimizing electrode-to-case fitment.
Quality Control:
Edge Inspection: High-quality slitters are designed to produce a near-perfect edge, which is continuously monitored to ensure burr-free production and prevent manufacturing defects.
Precision and Performance
Tension Control: Independent, closed-loop tension control systems on the unwinding and rewinding stations ensure the delicate electrode material is handled consistently, preventing the material from stretching, which would distort its density and performance.
Dust/Contamination Control: Designed with specialized systems to minimize carbon/active material dust generation during the cutting process, maintaining a clean environment critical for battery manufacturing.
Customization: The slitting knife system is adjustable to produce multiple pole-piece widths from a single master roll, offering great flexibility for R&D.
