Abstract

Benefiting from the unique structure of ultrafine NiSx nanospheres uniformly wrapped in the in situ S-doped rGO matrix, the NiSx–rGOS electrode delivers a high reversible capacity of 516 mA h g−1 at 0.2 A g−1 and a remarkable rate performance of 414 mA h g−1 at 4 A g−1, offering a low cost and high performance anode material for Na-ion batteries.
