Abstract

By a novel in situ chemical vapor deposition, activated N-doped hollow carbon-nanotube/carbon-nanofiber composites are prepared having a superhigh specific Brunauer-Emmett-Teller (BET) surface area of 1840 m2g-1and a total pore volume of 1.21 m3g-1. As an anode, this material has a reversible capacity of ∼1150 mAh g-1at 0.1 A g-1(0.27 C) after 70 cycles. At 8 A g-1(21.5 C), a capacity of ∼320 mAh g-1fades less than 20% after 3500 cycles, which makes it a superior anode material for a Li-ion battery.
