Abstract

Freestanding nanoporous N-doped graphene with encapsulated RuO2 nanoparticles is developed as a cathode for rechargeable Li-O2 batteries. The stabilized metal oxide catalyst reduces charge overpotentials enabling high-efficiency rechargeable Li-O2 batteries with a long cycling lifetime. This has important implications for the development of highly stable and catalytically active graphene-based cathodes for rechargeable Li-O2 batteries.
