Jens Reiser explaining how the thickness of battery foils is being measuring with CHRocodile 2 DPS

Measuring the thickness of battery foils - which challenges do you have to master?

The exact coating thickness of electrode foils plays an essential role as it significantly influences the performance, safety and lifetime of batteries.
Precitec 3D Metrology sensors allow comprehensive measurement of the calendering process.
The thickness of the electrode before and after calendering, the concentricity of the calender rollers and the so-called wrinkles at the edge of the coating are measured.
Vibrations of the films are compensated and waviness is offset.
Whether shiny copper or black, porous graphite - measurements can be realized with excellent accuracy and reproducibility at any time, even at high belt speeds of between 100 - 150 m/min.
