Abstract

A novel rod-like carbon-coated MnS electrode material (MnS/C) hybrid for sodium ions batteries (SIBs) was designed by annealing Mn-based metal-organic frameworks coupled with sulfur. When evaluated as anode material for SIBs, the typical MnS/C hybrid exhibits satisfied reversible capacity of 297 mAh g−1 after 100 cycles at 50 mA g−1, excellent rate capability (173.9 mAh g−1 at 1 A g−1 and 143.1 mAh g−1 at 2.5 A g−1) and robust long-term cycling stability (148.3 mAh g−1 after 5000 cycles at 1 A g−1), showing great potential for high-performance SIBs.
