Title (EN) IMPROVED ELECTROCHEMICAL CELLS FOR HIGH-ENERGY BATTERY USE
(FR) ÉLÉMENTS ÉLECTROCHIMIQUES AMÉLIORÉS DESTINÉS À ÊTRE UTILISÉS DANS UNE BATTERIE HAUTE ÉNERGIE
Abstract:
(EN) Components and structures for a rechargeable electrochemical cell and an electrochemical cell having an S02 solvent based electrolyte comprising any of said components and structures are provided. The cathode (2) may comprise one or more elemental transition metals and/or one or more partially oxidized transition metals. The S02 solvent based electrolyte (3) may comprise halide- containing salt additive as an SEI-forming additive. The anode current collector (5) may comprise a carbon coated metal, an alloy of two or more metals or a carbon coated alloy of two or more metals. The electrochemical cell may comprise excess non-dissolved/solid alkali halides. The components, structures and cell may bay used in a device.
(FR) L'invention porte sur des composants et des structures destinés à un élément électrochimique rechargeable et sur un élément électrochimique disposant d'un électrolyte à base de solvant S02 comprenant l'un quelconque desdits composants et structures. La cathode (2) peut comprendre un ou plusieurs métaux de transition élémentaires et/ou un ou plusieurs métaux de transition partiellement oxydés. L'électrolyte à base de solvant S02 (3) peut comprendre un additif de sel contenant un halogénure en tant qu'additif formant une SEI. Le collecteur de courant d'anode (5) peut comprendre un métal revêtu de carbone, un alliage de deux métaux ou plus, ou un alliage revêtu de carbone de deux métaux ou plus. L'élément électrochimique peut comprendre des halogénures alcalins non dissous/solides en excès. Les composants, les structures et l'élément peuvent être utilisés dans un dispositif.
