Graphene-Coated 1D MoTe2 Nanorods as Anode for Enhancing Lithium-Ion Battery Performance
文献摘要：
One-dimensional nanostructures(1D)with short ion diffusion distance and fast ion transport path are excellent for lithium-ion batteries(LIBs).However,the nature of layered transition metal dichalcogenides makes it difficult to form 1D nanohybrids.Here,the MoTe2 nanorods with an av-erage diameter of 100-200 nm and length of 1-3 μm encapsulated by reduced graphene oxide(MoTe2/rGO)have been fabricated via in-situ reaction of GO coated Mo3O10(C2H10N2)nanowires with Te under Ar/H2 atmosphere.When applied as anode of LIBs,the MoTe2/rGO delivers a high reversible capacity(637 mA h g-1 after 100 cycles at0.2 A g-1),good rate capability(374 mA h g-1 at 2 A g-1)and excellent stability(360 mA h g-1 after 200 cycles at 0.5 A g-1),which surpasses bare MoTe2 nanorods and bulk MoTe2 crystallite.Furthermore,a lithium-ion full cell constructed by coupling MoTe2/rGO anode and LiCoO2 cathode shows a capacity of 105 mA h g-1 at 0.1 C.The enhanced performance mainly benefits from the ad-vantages of 1D nanostructure,and meanwhile the rGO thin layers are able to improve the conductivity and maintain the structural stability.This work provides a simple pathway for the synthesis of 1D TMDs nanostructures for energy storage and conversion.
