Abstract

We report a facile synthesis method of preparing interconnected porous CaMnO3 nanostructures and their utilization as new cathode catalysts in rechargeable lithium-oxygen (Li-O2) batteries. The CaMnO3-based electrode enables much enhanced cyclability with a 620 mV smaller discharge-recharge voltage gap than that of the carbon-only cathode at a current rate of 50 mA gcarbon(-1). The improved performance is attributed to the high electrocatalytic activity of CaMnO3 with a porous nanostructure.
