The invention relates to a battery cell, in particular a lithium-ion battery cell, wherein compared to conventional battery cells, a number of components can be reduced. The battery cell has at least one winding element, two current collectors each electrically connected to one of the electrodes of the winding element, and a metal housing. In order to be able to establish an electrical contact between one of the electrodes of the winding element and the housing, one of the current collectors is specifically configured and arranged such that said current collector is in direct mechanical and electrically conductive contact with the housing. To this end, said housing contact current collector () can be provided with a suitably wide plate-shaped area (), which in edge regions () that are bent away at a right angle can rest against an interior wall of the housing of the battery cell in a planar manner, and can establish an electrical contact therewith.

A mechanical system has a component, which is movable under friction. An oscillating micromotion (dither) is impressed upon the component, which, if necessary, is added to a non-oscillating base motion of the component. It is provided that the micromotion (without the base motion that is additional, if necessary) is faster within a period of the oscillation in the one direction and is of shorter duration than in the opposite direction (asymmetrical dither).
