However, it is still a prominent challenge to construct a noble\u2010metal\u2010free SAC with low cost but high efficiency. Herein, a novel nitrogen\u2010doped graphene (NrGO) based SAC, immobilized with atomically dispersed single cobalt (Co) atoms (Co\u2010NrGO\u2010SAC), is reported for ORRs. In this 3D NrGO, the Co\u2010N\n                    <jats:sub>4<\/jats:sub>\n                    sites endow high\u2010efficiency ORR activity, and the 3D\u2010interconnected porous architectures of NrGOs guarantee numberous active sites accessibility.

Particularly, ZABs with Co\u2010NrGO\u2010SACs deliver remarkable power density (\u2248240\u00a0mW cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    ), super durability of over 233\u00a0h at 5\u00a0mA cm\n                    <jats:sup>\u22122<\/jats:sup>\n                    , outperforming noble\u2010metal\u2010based benchmarks.
