  • Patent number: 10287690
    Abstract: The invention relates to a method for producing an aluminum strip, in which the aluminum strip is coated with a sorption layer which has a binder and a sorbent. The object to propose a method for producing an aluminum strip coated with a sorption layer, by means of which an aluminum strip can be coated cost-effectively having constant performance characteristics with respect to the sorption of, for example, water vapor, is achieved according to the invention by means of a method for producing an aluminum strip coated with a sorption layer by applying a suspension to the aluminum strip in the coil-coating process, which in addition to a liquid comprises at least one binder, formed as a solid, and a sorbent, and by subjecting the aluminum strip, together with the applied suspension, to a drying process, in which the binder is activated.

  • Patent number: 9887044
    Abstract: The invention relates to a current collector foil for batteries, accumulators or capacitors, comprising a carrier material and at least one electrically conductive layer made from a metal. Moreover, the invention relates to a method for producing a corresponding current collector foil as well as to the advantageous use thereof. The object of providing a current collector foil for batteries, accumulators or capacitors, which is optimized in relation to the contact surface and the adhesive properties and which results in an improved service life, is achieved as a result of the fact that the at least one electrically conductive layer is produced at least partially by electrodepositing a metal and has a texture.

  • Publication number: 20140320992
    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.

  • Publication number: 20130309513
    Abstract: The invention relates to a strip or foil (1) made from aluminium or an aluminium alloy that has an external oxide layer. The object of providing a strip or foil made from aluminium or an aluminium alloy in which the thermal and/or electrical conductivity remains consistently high regardless of the formation of an aluminium oxide layer is solved by arranging thermally and/or electrically highly conductive functional particles on one or both sides of the strip or foil, which functional particles at least partly penetrate the oxide layer of on the strip or foil.

  • Patent number: 5098530
    Abstract: A carbon electrode surrounded by a protective globe in a fusion refining electrolysis process. The protective globe is self-supporting, gastight and thermally stable. The protective globe is spaced from the carbon electrode by a predetermined distance. Also, there is a predetermined distance between an end of the carbon electrode to be immersed in a melting bath and an open end of the protective globe through which projects the carbon electrode. A preheating process requires the electrode to be initially preheated over the melting bath, then its exposed end is immesered into the melting bath while not immersing the protective globe, and finally immersing both the electrode and the protective globe.
