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.
