The invention relates to polymer compositions that conduct lithium ions including the following ingredients: at least one ionic polymer from the polymerization of an ionic liquid, the cation of which bears at least one polymerizable function; at least one lithium salt; and at least one non-ionic polymer, the composition being a solid composition, i.e., a composition devoid of water and organic solvent(s). The invention also relates to the use of the polymer compositions for entering into the formation of electrolytic membranes of electrochemical lithium generators.

A device for managing an accumulator, including: a plurality of strain gauges including at least three strain gauges, the strain gauges being arranged to measure stresses along at least three distinct stress axes; a measuring device measuring strains undergone by each gauge along its stress axis; a reversible electrical switch; a calculating device controlling opening and closing of the electrical switch, depending on measurements carried out by the measuring device.

Device for managing an accumulator

A cathode for an electrochemical reactor including a diffusion layer and a catalyst layer. The cathode has bimetallic or multimetallic nanoparticles, dispersed in direct contact with the diffusion layer, at least one of the metals being chromium (Cr) wholly or partly in oxidized form. The cathode is fabricated by depositing the bimetallic or multimetallic nanoparticles on the diffusion layer by DLI-MOCVD in the presence of O.
