摘要：

Hydrous amorphous RuO2 nanoparticles supported on reduced graphene oxide were developed as a cathode material for non-aqueous Li-O-2 batteries, resulting in substantially reduced overpotential as well as excellent cycleability. A new type of nanoneedle-like Li2O2 morphology was produced during discharge. The enhanced catalytic activity can be attributed to the amorphous and hydrous nature of the catalyst.
