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.
