Abstract

A hybrid Li-ion/Li–oxygen cathode is demonstrated. With a stable ionic liquid electrolyte, the capacity of a conventional LiCoO2 cathode is greatly enhanced by the Li–oxygen mechanism. Furthermore, the Li-ion mode operation helps to improve the cyclability of the Li–oxygen mode. The Li–oxygen capacity can be a backup power source for occasional usage.
