Current collector for an electrochemical cell

A current collector (1) according to the invention has at least one substantially plate-like and preferably thin-walled core region (2). This core region contains at least one electrically conductive third material. The current collector also has a first surface region (3) comprising at least one fi...

More Information
Summary:A current collector (1) according to the invention has at least one substantially plate-like and preferably thin-walled core region (2). This core region contains at least one electrically conductive third material. The current collector also has a first surface region (3) comprising at least one first material. The current collector also has a second surface region (4) comprising at least one second material. In this case, the electrical conductivity of the first surface region is lower than that of the second surface region. Furthermore, this first surface region is bounded and/or spatially separated from this second surface region.
