Carbon nanocolumn arrays have been fabricated directly onto a titanium foil by a pulsed laser deposition (PLO) technique using graphite as a target. The sample has been characterized by scanning electron microscopy, high resolution transmission electron microscopy, selected area electron diffraction, and X-ray photoelectron spectroscope. The carbon nanocolumns with aspect ratio over 20:1 are composed of plenty of curved graphite sheets stacked parallel to the substrate. The initial discharge and charge capacities of these carbon nanocolumns are approximately 1060 and 670 mAh g(-1), respectively, at a rate of 0.1 A g(-1). A reversible capacity of approximately 315 mAh g(-1) is still retained after 50 cycles. The good electrochemical performance and high aspect ratio suggest that the carbon nanocolumn arrays are promising microelectrode for three dimensional microbattery applications.
