Abstract[English]
An electrolyte for electrochemical devices with an alkali-metal anode having an anode-active material comprising an alkali metal is disclosed in which the electrolyte includes at least one sulfonyl solvent and a co-salt system. The co-salt system includes a lithium cation primary salt at a relatively high concentration and a secondary salt at a relatively low concentration. The secondary salt and its concentration are selected to increase the solubility of the primary salt. The concentration of the secondary salt may be increased to increase the solubility of the primary salt until the presence of the secondary salt begins to diminish the overall performance of the electrolyte. The primary salt may comprise two or more lithium cation salts and the secondary salt may comprise two or more salts.[French]
L'invention divulgue un électrolyte pour dispositifs électrochimiques avec une anode en métal alcalin ayant un matériau actif d'anode comprenant un métal alcalin dans lequel l'électrolyte comprend au moins un solvant de sulfonyle et un système de co-sel. Le système de co-sel comprend un sel primaire de cation de lithium à une concentration relativement élevée et un sel secondaire à une concentration relativement faible. Le sel secondaire et sa concentration sont sélectionnés pour augmenter la solubilité du sel primaire. La concentration du sel secondaire peut être augmentée pour augmenter la solubilité du sel primaire jusqu'à ce que la présence du sel secondaire commence à diminuer la performance globale de l'électrolyte. Le sel primaire peut comprendre deux sels de cation de lithium ou plus et le sel secondaire peut comprendre deux sels ou plus.
