摘      要：Owing to the abundance and low price of sodium,researches on sodium-ion batteries(SIBs)as a lithiumion battery(LIB)alternative are emerging as a *** is crucial to develop electrode materials suitable for sodium *** recent years,two-dimensional(2 D)layered transition metal disulfide compounds(TMDs)have trigered interest in the realm of energy and environmental *** particular,MoSeis thought to be a suitable material for SIBs due to its wide original layer spacing and high ***,N-doped dual carbon-coated MoSewith multichannel paths(MoSe/multichannel carbon nanofibers(MCFs)@NC)is fabricated via electrospinning,followed by a selenation and carbonization *** existence of a 3 D conductive network,abundant void spaces,and sufficient electron transportation pathways are conducive to rapid and fast charge transfer kinetics under volume expansion *** applied in SIBs,the MoSe/MCFs@NC shows a high capability(319 mA hg^(-1)at 10 A g^(-1)),as well as good cycling stability(303 mA h g^(-1)after 1100 cycles at 10 A g^(-1)).Furthermore,coupled with the Na_(3)V_(2)(PO_(4))_(2)O_(2)F cathode,the full cell also exhibits excellent *** theoretical calculation of the MoSe_(2)/MCFs@NC confirms that the superiority of its SIB performance is owing to the strong interaction between the double-doped carbon and *** scheme provides a wide space for preparing high-performance electrode materials for SIBs.
