The invention relates to a capacitor with a layered construction on a base element having open pores with inner pore surfaces. The base element is electrically conductive at least in a part of the inner pore surfaces and therefore forms a continuous electrode. The electrically conductive part of the inner pore surfaces is nanostructured. In the capacitor a layer of a solid body electrolyte is directly arranged on the electrode and an electrically conductive counter-electrode layer forming a counter electrode is directly arranged on the solid body electrolyte. The counter electrode is applied as a thin layer so that within the open pores a continuous free space remains. The invention also relates to a construction element comprising a foam structure which is part of such a capacitor. The invention also relates to a method of manufacturing such a construction element.

Capacitor having coated pores

An electrochemical storage device for storing and providing electrical energy by means of its electrical capacitance comprises an electrode comprising an electrode basis, a counter electrode arranged with a distance to the electrode and comprising a counter electrode basis, and an electrolyte arranged between the electrode and the counter electrode and separating the electrode from the counter electrode. The electrode on the electrode basis and the counter electrode on the counter electrode basis each comprise a surface-enlarging structure. The electrode basis and the counter electrode basis extend in a common contact plane of the electrode and the counter electrode, where they each comprise parts of a conductive contact layer arranged on a non-conductive substrate. Furthermore, a method of manufacturing such a storage device is described.

Supercapacitors with oriented carbon nanotubes and method of producing them

A fin stabilizer for stabilizing a watercraft against rolling movements includes a main fin configured to be pivoted by a watercraft-side fin drive, a tail fin, and an elastically deformable connection between the main fin and the tail fin, the elastically deformable connection being configured to flex whenever a water force acting on the tail fin is greater than a predetermined amount.
