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.
