Abstract

We have synthesized PPP from benzen by chemical reaction. And then disordered carbon materials were obtained by heating-treating PPP in a nitrogen atmosphere for 1, 4, 8 and 12 hour at $700^{\circ}C$. The carbon prepared by heat treatment showed a broad x-ray diffraction peak around $2{\theta}=20^{\circ}$ having a property of disordered carbon. Carbon electrodes were charged and discharged at a current density of $0.25mA/cm^2$. In the result, PPP-based carbon obtained at $700^{\circ}C$ for 8h showed 605mAh/g of first discharge capacity and had a small hysteresis characteristic.
