Energy storage in these batteries is limited by the cathode and does not exceed 200 mA h g −1 [7]. The capacity of a lithium battery system can be enhanced remarkably by using a completely different approach which combines Li as anode directly with oxygen as cathode active material in a Li/oxygen cell [7], [8].
