Abstract: The technology described relates to a process for the safe dissolution of alkali metals, alkaline earth metals, and alloys predominantly comprising at least one thereof. The process comprises contacting the metal with a reaction inhibitor and water. In this process, the reaction inhibitor is selected from a hydrocarbon, a hydroxylated compound, and a mixture thereof. The uses of this process for the quantitative dissolution of metals and their analysis, for the destruction and stabilization of metallic residues, and for the recycling of batteries are also described.

Abstract: Polymers used as rolling lubricating agents, to compositions including said polymers, and to alkali metal films including the polymers or compositions on the surface(s) thereof. The use of said polymers and compositions is also described for strip-rolling alkali metals or alloys thereof in order to obtain thin films. Methods for producing said thin films, which are suitable for use in electrochemical cells, are also described. An improved lubricant according to formula I, which, for example, achieves enhanced conductivity, and/or enables the production of electrochemical cells having an improved life span in cycles.

Abstract: The present technology described relates to lithium-based alloy electrode materials used for the production of anode in lithium accumulators and processes for obtaining same. The alloy comprises metallic lithium, a metallic component X1 selected from magnesium and aluminum and a metallic component X2 selected from alkali metals, alkaline earth metals, rare earths, zirconium, copper, silver, bismuth, cobalt, zinc, aluminum, silicon, tin, antimony, cadmium, mercury, lead, manganese, boron, indium, thallium, nickel, germanium, molybdenum and iron. Processes for preparing electrode materials thus obtained and their uses are also described.

Abstract: Here is described an electrode material comprising an electrochemically active metallic film and an organic compound, e.g. an indigoid compound (indigo blue or a derivative or precursor thereof). Processes for the preparation of the electrode material and electrodes containing the material, as well as to the electrochemical cells and their use are also contemplated.

Abstract: Crosslinked polymers and their uses in electrochemical systems, for example, as electrolyte membrane, are described. More precisely, these crosslinked polymers are formed by the crosslinking of a random copolymer based on monomers of glycidyl methacrylate or acrylate and of poly(ethylene glycol) methyl acrylate or methacrylate with a volatile polyamine crosslinking agent.
