Why Precision Electrode Slitting Is Becoming a Competitive Advantage in Battery Manufacturing?

As the demand for EV, energy storage, and high-density consumer batteries accelerates, electrode slitting has moved from a simple mechanical process to a critical quality-control step. Today’s battery factories face tighter coating tolerances, thinner foils, and higher line speeds—and traditional slitting systems often become bottlenecks.

Pengjin Battery Calendering And Slitting Intergrated Machine achieves high-speed operation with flat material edges and consistent cuts through a high-precision knife shaft structure and stable tension control, effectively improving the consistency of the battery cells.

Key Technical Highlights:

Roll specifications (mm): 950–1200–1300–1500

Roll operation speed: 120m/min

Roll material: 9Cr3Mo

Roll surface hardness: ≥HRC66

Round fluctuation ≤1.0μm, Straightness ≤2.0μm

Synchronization accuracy ≤0.3‰

Roll bending device—8 roll bending cylinders, roll bending force 100 t, control accuracy ±0.5 T
