Abstract (en)

[origin: WO2018193010A1] In order to improve an electrode unit for an electrochemical cell, in particular for a battery, comprising an electrode and a current collector element, which is in areal contact with the electrode, in such a way that, in a battery, a current distribution can be measured in a spatially resolved manner, it is proposed that the current collector element comprises at least two current collector segments, which are isolated from one another, that the at least two current collector segments each have a first current collector segment contact area and that the first current collector segment contact areas are in areal contact with the electrode. Furthermore, an improved battery comprising two electrode units, which are isolated by a separator element in layer form, and also an improved method for producing an electrode unit are proposed.
