Classification: CPC B  Y | IPC B

Claim 29:
30. An electrochemical apparatus comprising:
a chamber comprising a negative electrode in electronic communication with an electroactive species in a reduced state, a non-aqueous electrolyte, and a stabilizing additive, wherein the chamber is configured to receive a fluid mixture comprising a Lewis acid gas,
wherein the electroactive species comprises:
an oxidized state, and
at least one reduced state wherein the electroactive species bonds with the Lewis acid gas to form an anion adduct,

wherein the stabilizing additive comprises a cationic Lewis acid, a hydrogen-bond donor, or a combination thereof, and
wherein the stabilizing additive is present in an effective amount to:
kinetically favor the forming of an anion adduct between the Lewis acid gas and the reduced electroactive species,
thermodynamically favor the forming of the anion adduct in a thermodynamic equilibrium between the anion adduct and the reduced electroactive species, or
kinetically favor the forming of the anion adduct between the Lewis acid gas and the reduced electroactive species and thermodynamically favor the forming of the anion adduct in the thermodynamic equilibrium between the anion adduct and the reduced electroactive species.
