以兰炭为原料,KOH为活化剂,利用微波辐射对兰炭进行脱氢、炭化、活化制备活性炭材料.采用X射线衍射（XRD）、傅里叶红外光谱（FTIR）,透射电子显微镜（TEM）等手段对材料的结构和形貌进行表征.通过恒流充放电、循环伏安（CV）对材料的电化学性能进行测试.结果表明：兰炭基活性炭用于锂离子电池负极材料具有优异的循环稳定性和良好的库伦效率.材料在充放电电流密度为200mA·g-1时,首次放电比容量达1 850mAh·g-1,循环60周后容量仍然保持在713.8mAh·g-1.

英文摘要：

Taking semi-coke powder as feedstock and KOH as activating agent,active carbon material was prepared by means of dehydrogenation,carbonization,and activation under microwave radiation.The structure and morphology of the material were characterized by means of X-ray diffraction（XRD）,Fourier transform infrared spectrometry（FTIR）,and transmission electron microscopy（TEM）.The galvanostatic charge-discharge and cyclic voltammetry（CV）were used to test the electrochemical performance of the activated carbon material.The results showed that semi-coke active carbon taken as lithium-ion battery cathode materials would have excellent cycling stability and high coulomb efficiency.The specific capacity of the active carbon material at initial charging-discharging with current intensity of 200mA·g-1 was up to1 850mAh·g-1,and it was still 713.8mAh·g-1 after 60 cycles.
