EL-CUT

High Precision Electrode Cutter

Accuracy and reproducibility of electrochemical tests depend not only on the choice of materials, but also on simple geometric / mechanical parameters. One sometimes neglected factor is the proper cutting of the electrodes. Torn and chipped electrode edges, even when not seen with the naked eye, inevitably cause current inhomogeneity and are thus likely to affect experimental results. Especially cycle life and impedance results are prone to such artefacts. Electrodes cut by conventional punching (stamping) with only one punch force show chipped edges and are not flat. In contrast, electrodes cut (fineblanked) with the EL-CUT are produced with three active forces (cf. sketch) and in tools with a few microns cutting clearance. The fineblanking process results in electrodes with clean cutting surfaces with no torn or chipped edges and being almost perfectly flat.
