Rechargeable metal nitric oxide gas battery

摘要

A metal-NxOy electrochemical cell is provided. The cell contains a partition which inhibits diffusion of NxOy+ active species from the cathode compartment to the anode compartment. Also provided is a rechargeable battery containing the metal-NxOy electrochemical cell. A vehicle system wherein NxOy from a combustion engine exhaust is fed to a metal-NxOy battery is additionally provided.
