Hydrothermal synthesis of carbon nanotube/cobalt oxide core-shell one-dimensional nanocomposite and application as an anode material for lithium-ion batteries

摘要: Abstract Carbon nanotube/cobalt oxide core-shell one-dimensional nanostructures were prepared via a hydrothermal synthesis method, in which nanosize cobalt crystals homogeneously coated on the surface of carbon nanotubes. The morphologies and crystal structures as-prepared nanocomposites analysed by X-ray diffraction, field emission gun scanning electron microscopy, transmission microscopy. When applied as anodes lithium-ion cells, exhibited an initial lithium storage capacity 1250 mAh/g stable 530 mAh/g over 100 cycles. good electrochemical performance could be attributed to nanocrystalline unique nanostructures.
