Carbon electrode with NiO and RuO2 nanoparticles improves the cycling life of non-aqueous lithium-oxygen batteries

A non-aqueous lithium-oxygen battery with a NiO-RuO2 nanoparticle-decorated carbon cathode not only catalyzes both the oxygen reduction and evolution reactions, but also promotes the decomposition of the side products, leading to a cycling life more than twice of that of the pristine carbon cathode.264
