摘要
Abstract
PANI coated r-GO/Fe3O4 composite material as anode material of lithium ion battery was prepared by the method of Hummers.By means of X-ray diffraction,constant charge and discharge test and electrochemical testing technique,the impact of the coating amount of PANI on the composition and properties of composite materials was researched.The results show that PANI in amorphous state is distributed in the r-GO/Fe3O4,and it doesn't transform the structure of r-GO/Fe3O4.The electrochemical performance of composite materials coated by PANI is improved,and when the coating amount of PANI is 0.15 mol,the impedance is minimal.The initial charge and discharge specific capacity are 569.332 and 645.720 mAh/g,and the coulomb efficiency achieves 86.8％,which remains above 98％ after 20 cycles.The capacity retention remains 81.1％,and the cycle efficiency is great.关键词
