Abstract
A method for producing a silicon anode for secondary batteries. Mesoporous silicon is used for the anode to provide space for volume expansion in the course of intercalation, especially of lithium ions. However, instead of coating a metal film with silicon, here metal is deposited onto a monocrystalline etched silicon wafer. It is essential that the silicon is monocrystalline and that the two flat sides of the wafer are (100)-oriented, i.e., perpendicular to the (100)-direction of the volumetric crystal.
