ABSTRACT:
A rechargeable lithium-ion cell contains a positive electrode, negative electrode, charge-carrying electrolyte containing charge carrying medium and lithium salt, and cycloaliphatic N-oxide compound dissolved in or dissolvable in the electrolyte. The N-oxide compound has an oxidation potential above the positive electrode recharged potential and serves as a cyclable redox chemical shuttle providing cell overcharge protection.
