摘要： We report a facile synthesis method of preparing interconnected porous CaMnO 3 nanostructures and their utilization as new cathode catalysts in rechargeable lithium-oxygen (Li-O 2 ) batteries. The CaMnO 3 -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 g carbon −1 . The improved performance is attributed to the high electrocatalytic activity of CaMnO 3 with a porous nanostructure. We report a facile synthesis method of preparing interconnected porous CaMnO 3 nanostructures and their utilization as new cathode catalysts in rechargeable lithium-oxygen (Li-O 2 ) batteries. 出版日期： 2014-01-14 資源來源： Royal Society of Chemistry 識別號： ISSN: 1359-7345 識別號： EISSN: 1364-548X 識別號： DOI: 10.1039/c3cc48207c
