Electrolyte for supercapacitor and high-power battery use

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 () may comprise one or more elemental transition metals and/or one or more partially oxidized transition metals. The S02 solvent based electrolyte () may comprise halide-containing salt additive as an SEI-forming additive. The anode current collector () 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.

Electrochemical cells for high-energy battery use

The present disclosure relates to aqueous all-copper redox flow batteries. This battery comprises at least one first and second half-cell compartments including the first and second aqueous electrolyte solutions comprising a copper compound and supporting electrolytes and a first and second electrodes. The battery further comprises external storage tanks for the electrolytes residing outside of the half-cell compartments, and means for circulating the electrolytes to and from the half-cells. There is a separator between the first and the second half-cell, and the half-cells of this battery are configured to conduct oxidation and reduction reactions for charging and discharging the battery.
