SnO2/SiO2复合材料的合成与电化学性能
Synthesis and electrochemical property of SnO2/SiO2 composite
摘要
Abstract
Nano-SiO2 microspheres were synthesized via sol-gel process, then SnO2 particles was coated on.The prepared composite was characterized by X ray diffraction and transmission electron microscopy,results showed that SnO2 was successfully coated on the surface of SiO2, and the composite still preserved the original good dispersion of SiO2 microsphere. The composite was then used as lithium ion battery anode material and its electrochemical property was tested, date showed that the composite had an excellent cycle performance. Compared with the pure SnO2,although the composite has a little lower charge-discharge capacity at first cycle. However,after 20 cycles its charge-discharge capacity was 105.6％ and 80.7％ more than the former, respectively. So the composite prepared by this method has a good application foreground.关键词
