Abstract: A method for producing an electrode having an electrically conductive base element on which there is arranged an active material comprising a silicon nanostructure includes introducing a precursor mixture comprising a silicon-containing material and a base matrix into a spinning unit, arranging an electrically conductive base body at a defined distance from a delivery device of the spinning unit, and delivering at least part of the precursor mixture from the delivery device to the base body. The method further includes applying an electrical voltage between at least part of the spinning unit and the base body so as to spin a silicon-containing nanostructure onto the base body, heat-treating the silicon-containing nanostructure, removing the heat-treated nanostructure from the base body, processing the removed nanostructure to a slurry, and applying the slurry to the base element to produce the electrode.

Abstract: An anode material for a galvanic element, in particular a lithium-ion cell. To improve the current density and thermal stability of galvanic elements, the anode material includes nanofibers made of a metal, a metal alloy, a carbon-metal oxide composite material, a carbon-metal alloy composite material, a conductive polymer, a polymer-metal composite material, a polymer-metal alloy composite material or a combination thereof. The nanofibers may be in the form a nanofiber netting, a nonwoven and/or a network and may be connected to a current conductor.

Abstract: A method for producing an electrode with an electrically conductive main body on which an active material having a silicon nano-structure is arranged includes introducing a precursor mixture having a silicon-containing material and a basic matrix into a spinning unit and arranging the main body at a defined distance from a discharge device of the spinning unit. At least part of the precursor mixture from the discharge device is discharged. An electrical voltage is applied between at least one part of the spinning unit and the main body for laminating a silicon-containing nano-structure on the main body. The silicon-containing nano-structure is then tempered. The method produces an electrode with an especially high capacity coupled with good cycle resistance. An energy store includes the electrode.
