The potential for long-term operation of a lithium-oxygen battery using a non-carbonate-based electrolyte.
Herein we demonstrate the feasibility of extended cycle operation of a Li-O(2) battery by simple control of the discharge/charge protocol. By avoiding electrolyte decomposition and the deep discharge state of the air electrode, we were able to construct a Li-O(2) cell capable of efficiently cycling over 50 times with high energy density.
