Bamboo-like porous carbon nanotubes (BCNTs) are prepared on a large scale through the pyrolysis of bamboo-like highly crosslinked polydivinylbenzene nanotubes. As anode materials for lithium-ion batteries, the BCNTs exhibit excellent electrochemical performance, attaining a high discharge capacity of 335 mA h g(-1) at a current of 100 mA g(-1). Even at a higher charge-discharge rate of 1000 mA g(-1), a high discharge capacity of 230 mA h g(-1) can be obtained for up to 300 cycles, which indicates the material has an excellent high-rate performance and cycle stability due to the separated hollow compartment structure and rich micropores on the surface of the BCNTs with the high BET surface area of 490.8 m(2) g(-1).
