Abstract: An electrolysis cell, in particular for producing aluminum, contains a cathode, a layer made up of liquid aluminum arranged on an upper side of the cathode, a melt layer, thereupon and an anode above the melt layer. The cathode has at least one opening extending vertically through the cathode, in which opening at least one current supply extending vertically through the opening and electrically connected to the anode and/or to the cathode is provided. The electrolysis cell contains at least one further current supply arranged outside of the opening of the cathode, which current supply extends in the vertical direction at least in certain sections and which current supply is electrically connected to the cathode and/or to the anode.

Abstract: A cable contains filaments containing carbon, surrounded by a sizing. The filaments surrounded by the sizing are covered by a matrix which is composed of a material containing at least one elastomer and/or at least one thermoplastic elastomer. The cable can be used, in particular for pulling a load, for example in a goods lift.
