| الوصف: | Transition metal sulfides demonstrate attractive potential for sodium storage owing to their high theoretical specific capacity and high reserve. However, the low conductivity and volume expansion deteriorate their high-rate performance and cycling stability. In this work, we construct NiS2/FeS heterostructure by growing Ni-based layered double hydroxide nanosheets on Fe-based Prussian Blue nanocrystals followed by gaseous sulfurization, giving rise to flower-like NiS2/FeS nanoparticles. The as-prepared nanocomposite exhibits good rate performance of 156 mAh g−1 at 50 A g−1 and long cycle life of 606 mAh g−1 at 5 A g−1 after 1,000 cycles, which are superior to the heterostructure-free counterpart of NiS2 and FeS. Density functional theory calculation further verifies that the enhanced electrochemical performance of NiS2/FeS is due to the existence of interface derived from the heterostructure. |
