The commercial mass production of bifunctional oxygen catalysts with high activity and stability is critical for constructing high-performance Li-O2 batteries, but remains challenging. Herein, we describe a protocol for the scalable fabrication of a 2D porous bifunctional electrocatalyst of Pt/RuO2/graphene by spatial confinement strategy, and elaborately evaluate its oxygen reduction reaction & oxygen evolution reaction for advanced Li-O2 batteries. We then detail the synthesis steps for preparing electrocatalyst materials followed by assembly and evaluation of the three-electrode systems and coin-type Li-O2 batteries.
