摘要
采用石墨烯掺杂的Cu-有机骨架化合物(Cu-MOF)复合材料(Cu-MOF/r GO)作为锂离子电池负极材料,研究其电化学性能.结果表明:在充放电电流密度为50 m A/g时,充放电循环50次后,材料的放电比容量可达到520m Ah/g.同时该材料也显示出较好的倍率性能和较高的库仑效率.Cu-MOF/r GO是一种具有前景的锂离子电池负极材料.
Probing the electrochemical response of r GO-doped Cu-MOF composite used as an anode in a lithium ion batteries（ LIBs） is focused in this work. In consequence,the resulting material as an anode for LIBs delivers a reversible capacity of 520 m Ah/g after 50 cycles at a current density of 50 m A/g with an excellent coulombic efficiency and rate performance. The result indicates that Cu-MOF/r GO composite is a promising anode material for lithium battery applications.
