Abstract: An electrical energy storage module for a vehicle includes at least one electrical energy storage battery that has at least one negative electrode at least partially composed of lithium-metal nitride. The electrical energy storage module also includes at least one ammonia sensor for detecting a release of ammonia due to the decomposition of the lithium-metal nitride of the negative electrode in the presence of air or humidity.

Abstract: The use of vanadium oxide iron and/or aluminium bronzes as a cathode material in electrochemical generators is described. The cathode material is a vanadium oxide bronze having formula: M.sup.1.sub.x1 M.sup.2.sub.x2 V.sub.2 O.sub.5, wherein M.sup.1 is a vanadium oxide bronze or iron, M.sup.2 is a metal different from M.sup.1 having valency n and chosen from alkali metals, alkaline earth metals, transition metals and aluminium, and x.sub.1 and x.sub.2 are such that 0.06.ltoreq.x.sub.1 .ltoreq.0.13; 0.ltoreq.x.sub.2 .ltoreq.0.20; and 0.27.ltoreq.3x.sub.1 .ltoreq.nx.sub.2 .ltoreq.0.39; and may be combined as a cathode (9) with an Li or Li alloy anode (5) and with an electrolyte consisting of lithium perchlorate in propylene carbonate.

Abstract: A cell operable at temperatures between 100.degree. C. and 200.degree. C. includes a non-aqueous electrolyte which comprises at least one solvent belonging to the class of aromatic or aliphatic linear sulfones. The negative active material of the cell may be lithium, for example, and its positive active material is selected from the group constituted by oxides, oxisalts, and sulfides. The electrolyte includes as a solvent, in particular, dimethylsulfone alone or mixed with other aromatic or aliphatic linear sulfones.
