High-strength battery electrode foil for the production of lithium-ion accumulators

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.

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.

Textured current collector foil

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.

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.
