SnO2/MCMB核壳负极材料的嵌锂性能
Intercalated-Li performance of SnO2/MCMB core-shell composite anode material
摘要
Abstract
Tin dioxide(SnO2) coating mesocarbon microbead( MCMB) core-shell structure material was prepared. MCMB was acid treated firstly,a small amount of SnO2 was deposited on the surface of MCMB through liquid method, then SnO2 nano-rods grown on the surface of MCMB by hydrothermal method. XRD,SEM and transmission electron microscope (TEM) tests were used to analyze the material. Galvanostatic charge-discharge and cyclic voltammogram experiments were used to study the material. When cycled in 0.001 ~ 2.000 V with the current of 100 mA/g, the initial charge and discharge specific capacity of the material was 1 038.4 mAh/g and 1 577.6 mAh/g,respectively,the specific discharge capacity was 581.9 mAh/g at the 25th cycle.关键词
