Abstract

We have investigated the effects of heat treatment on the electrochemical properties of carbon nanofibers (CNFs) for use as an anode material in lithium ion capacitors. The CNFs were fabricated by liquid-phase carbonization on a porous alumina template that was anodized in oxalic acid at 40V for 30min and subjected to a pore-widening process in phosphoric acid at room temperature. The CNFs were heated at temperatures of 600, 1000, and 1400 °C to facilitate rearrangement of the carbon structure.
