Popis: | MoSe2-MoO2@ honeycombed carbon composites have been obtained, in which the honeycombed carbon derived from sisal fiber services as a conductive matrix. The detailed preparation process is reported in this paper. The prepared composites are characterized by XRD, Raman, EDX, SEM and XPS analysis. It is obtained that the hybrid MoO2-MoSe2 with nanoparticle and hierarchical flower-like structures are coating on the surface of sisal fiber carbon (SFC). The electrochemical behavior of the lithium ion battery using MoO2-MoSe2@SFC as electrode has been studied. The electrode exhibits a retention capacity of 494 mAh/g at the current density of 50 mA/g over 30 cycles, while a capacity of 258 mAh/g is obtained at the current density of 1 A/g. The roles of the MoO2 and MoSe2 in electrochemical behavior are discussed respectively. |
