摘要

An efficient fluidization process intensification method was proposed to prepare carbon nanotube(CNT)-enhanced high-performance SiO anodes for lithium-ion batteries.The introduction of graphite particles decreased bonding among SiO particles,inhibiting agglomerate growth and enhancing fluidization.The(SiO+G)/CNTs composites were synthesized by fluidized bed chemical vapor deposition with the CNTs grown in-situ,which ensured uniform dispersion and superior anchoring of the CNTs.The in-situ-grown CNTs and stacked graphite ensured excellent structural stability and conductivity.The synthesized(SiO+G)/CNTs delivered a stable reversible capacity of 466 mAh g-1 after 125 cycles and a capacity of～200 mAhg-1 at 2 Ag-1.The charging results indicated that the 3D network structure comprising CNTs and graphite not only effectively buffered the electrode expansion but also greatly improved mechanical flexibility.
