loss after 130 cycles in lithium-matched full-cell tests against Li 4 Ti 5 O 12 anode), as well as a round-trip overpotential of only 0.24 V. Further, the cathode is automatically protected from O 2 gas release and overcharging through the shuttling of self-generated radical species soluble in the carbonate electrolyte. volts to 0.24

volt, and impressive rechargeability. While the results, reported in the journal Science , are promising, the researchers caution that a practical lithium-air battery still remains at least a decade away. mAh based on 1 mg of carbon and binder). LiO 2 cells are very sensitive to moisture and carbon dioxide.
