In situ synthesis of amorphous RuO2/AZO as a carbon-free cathode material for Li–O2 batteries

Abstract

The composite of amorphous RuO₂ as an electrocatalyst and aluminum-doped ZnO (AZO) as a cathode material was synthesised and developed into a carbon-free cathode material for Li–O₂ batteries for the first time. The amorphous RuO₂/AZO carbon-free cathode exhibits a noticeably reduced overpotential as well as an enhanced specific capacity.
