Abstract(summary):

Abstract Outstanding sodium and lithium storage capability is successfully demonstrated in ultrathin NiO nanosheets (4–5 nm in thickness) synthesized via a facile solvothermal process followed by annealing in air. For sodium storage, the NiO nanosheets deliver a high reversible specific capacity of 299 mA h g −1 at a current density of 1 A g −1 , and the capacity still remains up to 154 mA h g −1 at 10 A g −1 . Upon charge/discharge cycling, the specific capacity maintains to be as high as 266 mA h g −1 during the 100th cycle at 1 A g −1 . Such sodium storage capability of NiO nanosheets is by far one of the best reported for transition metal oxides. For lithium storage, the cell achieves a high reversible specific capacity of 1242 and 250 mA h g −1 at 0.2 and 15 A g −1 , respectively. The capacity for lithium storage maintains to be 851 mA h g −1 during the 170th cycle at 2 A g −1 . The present results demonstrate that ultrathin NiO nanosheets are highly attractive for fast sodium/lithium diffusion with high-rate capability for rechargeable sodium-ion batteries (SIBs) and lithium-ion batteries (LIBs). Graphical abstract Highlights • Ultrathin NiO nanosheets (4–5 nm in thickness) were synthesized. • NiO nanosheets show high capacity, good rate and cycle performance for Na + /Li + storage. • The sodium storage capability is one of the best reported for transition metal oxides. • The ultrathin morphology is critical for achieving fast and durable Na + /Li + storage.
