dc.description.abstract | Unique-structured MoS2-Ni9S8-C, MoSe2-NiSe-C, MoS2-Ni9S8, and MoSe2-NiSe-NiSe2 composite microspheres were prepared by pilot-scale spray drying and a subsequent post-treatment process. Dextrin, used as the carbon source, played a key role in the formation of unique-structured multicomponent metal sulfide and selenide microspheres with and without carbon. The empty nanovoids formed by decomposition (or carbonization) of phase-separated dextrin during the spray drying process were uniformly distributed within the multicomponent metal sulfide and selenide composite microspheres. The discharge capacities of MoS2-Ni9S8-C, MoSe2-NiSe-C, MoS2-Ni9S8, and MoSe2-NiSe-NiSe2 for the 80th cycle at a current density of 0.5 A g(-1) for sodium-ion storage were 366, 386, 459, and 291 mA h g(-1), respectively, and the respective capacity retentions measured from the second cycle were 91, 102, 92, and 64%. The carbon-free MoS2-Ni9S8 microspheres exhibited excellent rate performance and their discharge capacities decreased slightly from 559 to 428 mA h g(-1) as the current densities increased from 0.1 to 3 A g(-1). The MoS2-Ni9S8-C composite microspheres, with high structural stability during repeated sodium-ion insertion and deinsertion, showed extremely long-term cycling performance for 1000 cycles. | - |
