摘要
采用新颖绿色的电化学阴极腐蚀法合成了Sb_2O_3/氮掺杂石墨烯复合材料。XRD及TEM表征结果表明复合材料中Sb_2O_3纳米颗粒均匀地附着在氮掺杂石墨烯表面。该复合材料应用于锂离子电池负极材料具有较好的电化学储能性能,其可逆容量达到527 mAh/g,50次循环之后的容量保持率高达90.1%。
A green and novel method,cathodic corrosion,has been adopted to prepare Sb_2O_3/nitrogen-doped graphene composite.XRD and TEM results show that the Sb_2O_3 nanoparticles are dispersed uniformly on the nitrogen-doped graphene sheets.The as-fabricated composite used as anode material for lithium-ion battery shows enhanced electrochemical performance.The reversible capacity is as high as 527 mAh/g and the capacitance ratio can reach 90.1%after cycling against lithium for 50 cycles.
