摘要： A metallic lithium rechargeable electrochemical accumulator, including at least one lithium metal electrode and at least one polymeric electrolyte gel. The 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 wherein a particularly long life, even with intensive use at low temperature. The 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, the 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： Particles including a core and a coat covering at least part of the core surface. The core has more than 50% of an acidic metal oxide and the core coating is based on a polymer, preferably based on a solid polymer with high electrochemical stability. The particle has a solubility rate (ds), in fixed time, of the metal oxide migrating towards the electrolyte, per cycle, which is less than 5 per 10000. The particles are obtained by mixing the polymer and a metal oxide, via dry process with addition of solvent. The electrodes constituting an electrode substrate at least partly coated with a mixture consisting of at least 40 of those particles have remarkable electrochemical properties, in particular regarding the lifetime of batteries in which they are incorporated.
