Superior Performance of a Li–O 2 Battery with Metallic RuO 2 Hollow Spheres as the Carbon‐Free Cathode

Superior Performance of a Li–O 2 Battery with Metallic RuO 2 Hollow Spheres as the Carbon‐Free... Hierarchically porous, metallic RuO2 hollow spheres are applied as a carbon‐free cathode for Li–O2 batteries for the first time. They exhibit low charge potentials of ≈3.5 V, corresponding to overpotentials of 0.13/0.54 V in discharging and charging processes, a large reversible capacity of ≈1400 mAh g−1, and 100 cycles of full discharge and charge. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Energy Materials Wiley

Abstract

Hierarchically porous, metallic RuO2 hollow spheres are applied as a carbon‐free cathode for Li–O2 batteries for the first time. They exhibit low charge potentials of ≈3.5 V, corresponding to overpotentials of 0.13/0.54 V in discharging and charging processes, a large reversible capacity of ≈1400 mAh g−1, and 100 cycles of full discharge and charge.
