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.Keywords
