Electrode, method for producing an electrode and energy store having an electrode

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.
