  • Publication number: 20220223855
    Abstract: A method for producing silicon-based anodes for secondary batteries carries out the following steps for producing an anode: —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, —heating the metal substrate using a heating unit to a temperature between 200° C. and 1000° C., —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, 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—generating crystalline metal of the metal substrate.

  • Patent number: 10147824
    Abstract: A capacitance diode or variable capacitance diode includes first and second electrodes and a layer configuration disposed in contact-making fashion between the two electrodes. The layer configuration has, one after the other in a direction from the first electrode towards the second electrode, a layer formed of a ferroelectric material and an electrically insulating layer formed of a dielectric material having electrically charged defects. A method for producing a capacitance diode or a variable capacitance diode, a storage device and a detector including a capacitance diode or a variable capacitance diode are also provided.
