Discharge state assembled rechargeable electrochemical cell comprizing metallic electrodes

The present application relates to an electrochemical cell comprising a nitrile-based solvent based electrolyte, wherein

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

An electrochemical cell for a secondary battery, preferably for use in an electric vehicle, is provided. The cell includes a solid metallic anode, which is deposited over a suitable current collector substrate during the cell charging process. Several variations of compatible electrolyte are disclosed, along with suitable cathode materials for building the complete cell.
