The core element and the stator for an electric machine, electric machine, plate on a core element, method for producing a capacitor and method for storing electric energy

Disclosed is a core member (106) for a coil of an electrical machine. The core member (106) comprises a first plate (200) of an electrically conductive material, a second plate (202) of an electrically conductive material and an electrically insulating adhesive layer, the adhesive layer between the first plate ((200) and the second plate 202) and the first plate (200) connects to the second plate (202). The first plate (200) has a first electrical contact element (206) and the second plate (202) includes a second electrical contact element (208) for using the core member (106) than a capacitor.
