Lithium-air batteries using Ketjen Black-EC600JD for their air electrodes exhibited a rather large discharge capacity of about 3000 mAh g－1 at a current density of 0.05 mA cm－2. However, the cycle performance of the batteries was very poor due to the high overpotential for charging. The cycle properties were greatly improved by adding the Fe–Mn-based perovskite-type oxide, La0.6Sr0.4Fe0.6Mn0.4O3, to the air electrodes as an electrocatalyst.
