The construction of molybdenum disulfide/cobalt selenide heterostructures@N-doped carbon for stable and high-rate sodium storage
文献摘要：
Constructing heterostructures is an important approach to develop high-performance anode materials for sodium ion batteries(SIBs).The abundant phase interfaces provide numerous defects and active sites for rapid electron/ion transport.Herein,CoSe2 ? NC@NC/MoS2 heterostructures are prepared through a multi-step reaction strategy,CoSe2 nanoparticles served as the coating shells for MoS2 cores are anchored in carbon frameworks.The core-shell structure effectively buffers the double volume expansion and inhi-bits the dissolution of MoS2 and CoSe2 in the electrolyte.As SIBs anodes,the heterostructure delivers a high reversible capacity of 481.6 mAh g-1 at 0.5 A g-1 after 100 cycles,superior rate capability(174.5 mAh g-1 at 20.0 A g-1),excellent long-term cycle performance(333.4 mAh g-1 after 2000 cycles at 5.0 A g-1).The DFT calculation proves that the electronic distribution of heterostructures is reconstructed with enhanced conductivity.The kinetic analysis,mechanism characterizations and full-cells tests exhibit the synergistic reaction mechanism among different components and practical application prospects.The heterostructure also shows more rapid ions diffusion kinetics than single components.
