采用比表面吸附(BET)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射光谱(XRD)、激光拉曼光谱(Raman)等手段,对掺杂ZnCl2的酚醛树脂热裂解炭材料进行了表征.结果表明:该材料的微粒及孔径均为纳米级,平均微粒径在40～60nm,平均孔径为3.86nm.用该材料做电极,经过30次充放电循环,可逆容量为360mA·h·g-1.

Phenolic resin-based nanoscopic carbonaceous materials have been prepared by doping different proportions of ZnCl2 into phenolic resin precursor at various heat-treatment temperatures and characterized by means of Brunner-Emmett-Teller method (BET), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and Raman spectroscopy analyses.The results show that the average size of grains and apertures is from 40 to 60 nm and 3.86 nm, respectively, reaching nanometer level.When the material was used as electrode material of lithium ion battery, the reversible capacity could be kept at 360 mA·h·g-1 after 30 charge/discharge cycles.

Key words: phenolic resin, carbonaceous material, lithium ion battery, ZnCl2
