| 摘 要： | 以竹笋为原料炭化获得生物质炭，再用氢氧化钾活化得到多孔生物质炭，采用扫描电镜（SEM）、透射电镜（TEM）、X射线衍射（XRD）和氮气物理吸附等方法对多孔生物质炭的微观结构和形貌进行了表征。以此多孔生物质炭作负极材料探究其电化学性能，结果表明在1 000 mA/g电流密度下，材料的首次充电比容量为286.9 mA·h/g，循环50次后充电比容量保持在201.8 mA·h/g，循环500次后充电比容量仍有221.5 mA·h/g，表明此多孔炭材料具有优良的电化学循环性能，使其有望成为具有竞争力的锂电池负极材料。

| Abstract: | Bamboo shoots were used as raw material to carbonize to obtain biomass charcoal，and then activated with KOH to obtain porous biomass charcoal.The microstructure and morphology of porous biomass charcoal were characterized by scanning electron microscope（SEM），transmission electron microscope（TEM），X-ray diffraction（XRD） and physical adsorption of nitrogen，etc.By using this porous biomass carbon as a anode material to explore its electrochemical performance，the results showed that at a current density of 1 000 mA/g，the first?round charging specific capacity was 286.9 mA·h/g，and after 50 cycles，the charging specific capacity remained at 201.8 mA·h/g.After 500 cycles，the charging specific capacity was still 221.5 mA·h/g，indicating that the porous carbon material had excellent electrochemical cycling performance，making it a promising anode material for lithium batteries. |
