Abstract

The NiS₂ nanosheet array on Ni foil (NiS₂/NF) was prepared using an in situ growth strategy and sulfidation method and was used as the cathode of lithium sulfur battery. The unique nanostructure of the NiS₂ nanosheet array can provide abundant active sites for the adsorption and chemical action of polysulfides. Compared with the sulfur powder coated pure NF (pure NF-S) for lithium sulfur battery, the sulfur powder coated NiS₂/NF (NiS₂/NF-S) electrode exhibits superior electrochemical performance. Specifically, the NiS₂/NF-S delivered a high reversible capacity of 1007.5 mAh g⁻¹ at a current density of 0.1 C (1 C= 1675 mA g⁻¹) and kept 74.5% of the initial capacity at 1.0 C after 200 cycles, indicating the great promise of NiS₂/NF-S as the cathode of lithium sulfur battery. In addition, the NiS₂/NF-S electrode also showed satisfactory electrochemical performance when used as the cathode for sodium sulfur battery. © 2021, Science China Press and Springer-Verlag GmbH Germany, part of Springer Nature.
