The battery includes a negative electrode and a positive electrode separated by an electrolyte, wherein the negative electrode consists of a film of metal material selected from among lithium and lithium alloys, the positive electrode includes a film of a porous carbon material on a current collector, and the electrolyte is a solution of lithium salts in a solvent. The battery is characterized in that the surface of the negative electrode opposite the electrolyte has a passivation layer containing Li
2 S, Li
2 S
2 O
4 , Li
2 O, and Li
2 CO
3 , the passivation layer being richer in sulfur compound on the surface thereof that is in contact with the electrolyte. The battery is obtained by means of a method consisting of producing the positive electrode, the electrolyte, and a film of the metal material for forming the negative electrode, and assembling the positive electrode, the electrolyte, and the film of metal material. The method is characterized in that it includes a step of subjecting the film of metal material to a gaseous atmosphere containing SO
2 , before or after the assembly thereof with the positive electrode and the electrolyte.

摘要： The invention relates to a metallic lithium rechargeable electrochemical accumulator, comprising at least one lithium metal electrode and at least one polymeric electrolyte gel. Said accumulator is capable of operating at temperatures from - 20 to 60 °C, essentially without formation of lithium dendrites on the whole surface of the metallic lithium electrode. The above is also characterised by a particularly long life, even with intensive use at low temperature. Said inventive rechargeable accumulator can be produced by use of a production method with particular application of temperature control during the specific production stages. As a result of the extremely high electrochemical performance of said accumulator, in particular the remarkable stability thereof, said accumulator can be used in new application fields such as hybrid vehicles, electric vehicles and emergency supply systems such as those of the UPS type.

摘要： The invention relates to a method of preparing surface-purified graphite particles from particles of an impure graphite. The inventive method comprises at least one step whereby the graphite particles are treated with a dilute aqueous solution of (H2SO4 and NH4F). According to the invention, the H2SO4 and the NH4F each have a weight content in the dilute aqueous solution of between 5 and 30 % of the total weight of said solution, while the quantity of the dilute aqueous solution represents between 70 and 95 % of the weight of the graphite particles to be purified.
