采用溶胶-凝胶技术在富锂锰基固溶体Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 表面包覆V 2 O 5 , 制备了Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 @ V 2 O 5 核壳复合材料。通过扫描电镜(SEM)和透射电镜(TEM)观察其形貌, X射线衍射(XRD)分析确定其结构。结果显示, 结晶态的V 2 O 5 均匀包覆在类球形Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 颗粒表面, Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 材料的晶体结构在包覆前后保持不变。X射线光电子能谱(XPS)分析结果表明, 该核壳复合材料首次充电时, 锂离子嵌入V 2 O 5 包覆层。电化学测试结果表明, 表面包覆15%V 2 O 5 的核壳复合材料具有最佳的电化学性能: 0.1 C 倍率下放电比容量为276 mAh/g, 首次充放电库仑效率达到94%, 50次循环后容量保持率达89%。采用溶胶-凝胶技术在富锂锰基固溶体Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 表面包覆V 2 O 5 , 制备了Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 @ V 2 O 5 核壳复合材料。通过扫描电镜(SEM)和透射电镜(TEM)观察其形貌, X射线衍射(XRD)分析确定其结构。结果显示, 结晶态的V 2 O 5 均匀包覆在类球形Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 颗粒表面, Li 1.2 Mn 0.54 Co 0.13 Ni 0.13 O 2 材料的晶体结构在包覆前后保持不变。X射线光电子能谱(XPS)分析结果表明, 该核壳复合材料首次充电时, 锂离子嵌入V 2 O 5 包覆层。电化学测试结果表明, 表面包覆15%V 2 O 5 的核壳复合材料具有最佳的电化学性能: 0.1 C 倍率下放电比容量为276 mAh/g, 首次充放电库仑效率达到94%, 50次循环后容量保持率达89%。
