摘　　要：对可溶性酚醛树脂进行 Zn Cl2 掺杂 ,详细讨论了 Zn Cl2 的掺杂对酚醛树脂炭材料结构和性能的影响 .采用 X射线衍射 ( XRD)、扫描电子显微镜 ( SEM)、拉曼光谱 ( Raman)及表面吸附实验 ( BET)等测试手段 ,对掺杂 Zn Cl2 后的炭化物进行了结构表征及电化学性能测试 .结果表明 ,掺入 Zn Cl2 后炭化物的微晶尺寸和层间距变大 ,微粒大小趋于均匀 ,微粒及微粒内部孔径均为纳米级 ,孔径明显增大 ,比表面积大幅度地增加 .用该热 (裂 )解材料作电极 ,其可逆容量达 745 m A· h/g.The influence of ZnCl 2 doping on the structure and properties of carbonized phenolic resin material was investigated in detail. The structure and electrochemical properties of the carbonaceous material were measured by means of XRD, SEM, BET and Raman analyses, respectively. The results show that after doping ZnCl 2, the crystallinic size and distance between layers become larger, the partical size also tends to be uniform, the apertures and specific surface area of the product tend to be uniform, the apertures and specific and specific surface area of the product are obviousely increased. Moreover, the product size and internal aperture are all in nano-level range. By using this carbonaceous product as the electrode material, the reversible discharge capacity of the battery can reach 745 mA·h/g.
