摘要：

Porous carbon materials derived from plane tree leaves were prepared via a facile high -temperature carbonization method. The plane tree leaves were activated by KOH solution, and then carbonized under nitrogen atmosphere protection at 500 degrees C, 600 degrees C, 700 degrees C and 800 degrees C respectively. The obtained porous carbon materials were characterized in detail by scanning electron microscope (SEM), X-ray powder diffractometer (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy and BET analysis. The electrochemical properties of the materials were analyzed by galvanostatic charge -discharge test and electrochemical impedance spectroscopy (EIS). Due to the unique porous structure and high active surface, the sample carbonized at 700 degrees C displayed the highest reversible specific capacity of 460.4 mAh/g at a current density of 50 mA g-1, and maintained a specific capacity of 242 mAh/g even at a high current density of 2000 mA g- 1.
