We demonstrate that 9,10-Bis(2-methoxyethoxy)-1,2,3,4,5,6,7,8-octahydro-1,4:5,8-dimethanoanthracene redox shuttle molecule survives over 120 cycles with 100% overcharge ratio at C/5 rate in litium-ion batteries. Equally remarkably, in the presence of this electrolyte additive, the cell impedance becomes significantly lower compared to the control cells without this additive during the formation, normal cycling, and even under overcharge conditions.
