ABSTRACT:
A rechargeable electrochemical cell comprising a cathode, a liquid electrolyte with a solute and at least one solvent, an anode containing a highly crystallized carbon-containing material capable of intercalating lithium ions, said electrochemical cell being characterized by the fact that the surface of said carbon-containing material is provided with a thin layer which is impermeable to said electrolyte solvent, but which allows lithium to be diffused.
