酚醛树脂炭包覆天然微晶石墨作锂离子电池负极材料 李富进1,徐乐1,刘洪波1,何月德2 (1.长沙理工大学物理与电子科学学院,湖南,长沙,410014;2.湖南大学材料科学与工程学院,湖南,长沙,410082) 摘要:通过酚醛树脂包覆天然微晶石墨和炭化处理制备具有核壳结构的酚醛树脂炭包覆天然石墨负极材料,考察了酚醛树脂包覆量对酚醛树脂炭包覆天然石墨负极材料结构和性能的影响.结果表明,表面树脂炭的存在使石墨表面更光滑,但不会改变其片层状晶体结构.酚醛树脂炭包覆石墨的比表面积随酚醛树脂包覆量的增加而增大.包覆适当厚度的酚醛树脂炭可明显改善天然微晶石墨的首次充放电性能和循环性能,酚醛树脂包覆量为3%的酚醛树脂炭包覆石墨的首次可逆容量为334.3mAh/g,首次充放电效率为84.8%. 关键词:锂离子电池; 负极材料; 天然微晶石墨; 酚醛树脂; 电化学性能; Li-ion battery......
