Electrolyte additives are described that enhance cycling stability of electrolytes and lithium composite electrodes that prolong cycling lifetimes and improve electrochemical performance of lithium ion batteries. The electrolyte additives minimize voltage fading and capacity fading observed in these batteries by reducing accumulation of passivation films on the electrode surface.
