A method for producing silicon-based anodes for secondary batteries carries out the following steps for producing an anode: &#x2014;depositing a silicon layer on a metal substrate having grain boundaries, wherein the silicon layer has a first boundary surface directed towards the metal substrate, &#x2014;heating the metal substrate using a heating unit to a temperature between 200&#xb0; C. and 1000&#xb0; C., &#x2014;conditioning the region of the second boundary surface of the silicon layer that is facing away from the metal substrate using an energy-intensive irradiation during the heating, &#x2014;generating polyphases in the region of the silicon layer and the metal substrate, made up of amorphous silicon and/or crystalline silicon of the silicon of the silicon layer and of crystalline metal of the metal substrate and of silicide and&#x2014;generating crystalline metal of the metal substrate.
