    摘要: Provided is a rechargeable lithium-ion cell that contains a positive electrode, a negative electrode, a charge-carrying electrolyte containing a charge carrying medium and a lithium salt, and a triphenylamine compound dissolved in or dissolvable in the electrolyte. The triphenylamine compound has an oxidation potential above the positive electrode recharged potential and serves as a cyclable redox chemical shuttle providing cell overcharge protection. Also provided are methods for manufacturing a rechargeable lithium-ion cell.
