摘要
High-purity vertically aligned carbon nanotubes (CNTs) were prepared on a quartz substrate by thermal chemical vapour deposition (CVD). The as-prepared carbon nanotubes have an outer diameter of 40–60 nm and a length of 70–80 μm. HRTEM observation revealed that there were compartment structures in the carbon nanotubes. The vertically aligned CNTs exhibit a high reversible lithium storage capacity of 950 mAh/g in lithium-ion cells.
