Abstract: The invention relates to a current collector foil made of aluminum or an aluminum alloy, to the use of the current collector foil for batteries or accumulators, in particular lithium-ion accumulators, and to a method for producing the current collector foil. The object of providing a current collector foil, which has very good properties with regard to conductivity and tensile strength, and which can also be produced economically, is achieved in that the current collector foil has an acid-pickled or alkali-pickled surface.

Abstract: The invention relates to a mirror comprising a reflective surface formed from a composite of a reflective film and a substrate, wherein the reflective film is disposed on the substrate and comprises at least one polymer layer and a metal layer disposed underneath the at least one polymer layer. It is the requirement of the invention to propose a mirror which can be manufactured in a simple way and at the same time comprises an improved corrosion behaviour. According to a first teaching of the present invention the stated requirement is met in that a sealing seam is provided for corrosion protection at least in certain areas, the sealing seam being formed by bonding the polymer layer to the substrate in a material-locking manner, wherein the metal layer is interrupted in the area of the sealing seam.

Abstract: The invention relates to a method for manufacturing a trough mirror for a solar trough, in particular longitudinal solar trough mirrors for solar power stations. One object is to provide a method for manufacturing a trough mirror for a solar trough mirror power station which reduces the costs for installing the solar power station.
