Carbon materials have been widely used to form cathodes for non-aqueous lithium-oxygen batteries. A critical problem with the use of carbon in this type of battery, however, is corrosion. To address this issue, we propose and fabricate a non-carbon cathode electrode consisting of MnO2-deposited stainless steel (SS) felts. Amorphous MnO2layer are electrodeposited on the surfaces of SS fibers at an anodic current in a manganese acetate solution. The use of the MnO2-SS electrode in a non-aqueous lithium-oxygen battery delivers a specific capacity of 1780mAhgMnO2-1. Furthermore, the discharge/charge cycle test with a fixed capacity of 500mAhgMnO2-1 shows that this electrode can discharge/charge for more than 10 cycles without degradation. It is, therefore, expected that this novel non-carbon and stable cathode is a promising electrode for high-performance lithium-oxygen batteries.
