Precision Guilloting Knives for Lithium Battery Electrode Processing

封面

Introduction

In lithium battery manufacturing, electrode cutting accuracy directly affects cell consistency, assembly quality and production stability.

Lithium battery guilloting knives are mainly used for transverse cutting processes, including electrode roll-to-sheet cutting, coated electrode sheet separation and trimming before battery assembly.

Unlike continuous slitting, guilloting requires the blade to complete full-width cutting with stable force and high edge accuracy. Poor cutting performance may cause burrs, coating damage, edge deformation and particle contamination, increasing production risks.

Guilloting Knives vs Circular Knives

Both guilloting knives and lithium battery slitting knives are important tools in electrode processing, but they are used for different cutting directions.

Circular knives are mainly used for longitudinal slitting. They divide wide electrode rolls into narrow strips during continuous roll-to-roll production. Their key requirements are high wear resistance, stable cutting performance and long service life.

Guilloting knives are used for transverse cutting, such as separating electrode sheets after coating or preparing electrodes before stacking. Since the blade cuts across the full electrode width, it requires precise edge design and stable cutting force.

Common Electrode Cutting Problems

During electrode cutting, battery manufacturers often face burr formation, unstable dimensions and particle generation.

Worn blades or improper cutting conditions may damage copper foil, aluminum foil and coated materials. Precision electrode cutting knives with optimized edge geometry help reduce burrs and maintain clean cutting surfaces.

How to Select

The right guilloting knife for lithium battery processing should be selected according to:

  • · Electrode material, such as copper foil, aluminum foil and coated electrodes
  • · Material thickness and cutting speed
  • · Machine type and production requirements
  • · Required tool life

A suitable knife design helps manufacturers achieve stable cutting quality and reduce production downtime. Shengong provides one-stop solutions and customizes cutting tools according to customers’ specific conditions.
