| 摘 要： | 为提高石墨作为锂离子电池负极材料的性能,将石墨进行氧化处理后,利用原位液相沉积法制备SnO2/石墨插层复合材料。利用红外、X射线衍射仪及扫描电镜等手段对所制备的材料进行表征。结果表明:石墨经氧化处理后,生成大量的极性基团,层间距扩大;原位液相沉积过程中,SnCl2.2H2O插入氧化石墨层间与氧化基团反应,生成SnO2;经过热处理,SnO2的结晶度得到提高,并均匀地分散在石墨层间。 |

| Abstract: | This paper presents an attempt to improve the performance of graphite anode material for lithium-ion battery by subjecting graphite to oxidation to prepare SnO2 /graphite intercalation composite by in-situ liquid phase deposition.The paper describes the use of FTIR,XRD and SEM to characterize the composite’s structure and morphology.Results show that the graphite layers subjected to oxidation turn into many polar functional groups with enlarging layer distance.In-situ liquid phase deposition allows SnCl2,2H2O to be inserted between layers of graphite oxide layers to react with the oxidation groups,thus generating SnO2.Heat-treated SnO2 has a better crystallinity and boasts a better uniformity between the graphite interlamination. |
| Keywords: | graphite SnO2 intercalation composite in-situ liquid phase deposition method |
