| 摘 要： | 在球形石墨上采用氧化—浸渍—固化—炭化的方法沉积一层酚醛树脂热解炭,制备成包覆石墨,对包覆石墨电化学性能进行了研究。通过对不同包覆量的复合材料的表观形貌、结构及其电化学性能的研究,对比包覆氧化石墨和未氧化石墨的电化学性能,得到结论:树脂炭对于氧化后的球形石墨具有较好的包覆作用,提高了球形石墨的球形度,有利于锂离子的嵌入/脱出,改善了电化学性能。

| Abstract: | The coated graphite were treated with phenol resin as coating agent to prepare composite anode material,which oxides in H2O2,involves liquid-phenol-impregnation and carbonization steps.According to research for the morphology,structure and charge-discharge performance and the electrochemical performance between the oxidized and no-oxidized natural graphite,the conclusion show that the pyrolysis of resin could coat graphite satisfactorily,and improve the surface of graphite,which helps to improve lithium ion insertion/deinsertion performance of natural graphite. |
