Abstract: A metal foil including on at least one of its sides a layer of a material including: a metal or a metal alloy, carbon, hydrogen, and optionally oxygen, the atomic percentage of the metal or of the metals of the alloy in the material ranging from 10 to 60%, the atomic percentage of carbon in the material ranging from 35 to 70%, the atomic percentage of hydrogen in the material ranging from 2 to 20%, and the atomic percentage of oxygen if present in the material being less than or equal to 10%. The metal foil can be used in the manufacture of a cathode of a lithium-ion electrochemical cell. The deposition of this layer reduces the internal resistance of the cell.

Abstract: The invention relates to a system (2) for producing an optical mask (35) for surface microtexturing, said system (2) comprising: a substrate (10) having a surface (11) that is to be textured; a layer of material (20) which covers the surface (11) of the substrate (10) and has an outer surface (21) that is exposed to the outside environment; and a generating and depositing device for generating and depositing droplets (30) on the outer surface (21) of the layer of material (20), in a specific arrangement (31) under condensation, forming the optical mask (35) on the outer surface (21) of the layer of material (20). The invention also relates to a treatment plant comprising a system (2) of said type. The invention further relates to a method for producing a mask as well as to a surface microtexturing method.
