An electrode for lithium ion batteries, the electrode having a metal film which is inert to lithium ions and having a plurality of silicon nanowires protruding from the film, which are arranged on at least one flat side of the film, wherein sections of the nanowires are enclosed by the metal film.

Electrode for lithium ion batteries

To reduce and homogenize the thickness of a semiconductor layer which lies on the surface of an electrically insulating material, the surface of the semiconductor layer is exposed to the action of an etchant whose redox potential is adjusted as a function of the material and the desired final thickness of the semiconductor layer, so that the material erosion per unit time on the surface of the semiconductor layer due to the etchant becomes less as the thickness of the semiconductor layer decreases, and is only from 0 to 10% of the thickness per second when the desired thickness is reached. The method is carried out without the action of light or the application of an external electrical voltage.
