摘要
Abstract
The graphite oxide with high tap-density was used as the cathode material of lithium-ion electrochemical capacitor.The acquired material was confirmed by X-ray diffraction (XRD),Raman spectroscopy,X-ray photoelectron spectroscopy (XPS),galvanostatic charge/discharge test,and so on.The results demonstrate that the graphite oxide can deliver higher specific capacity than active carbon and graphite,due to large amount of the oxygen-containing functional groups.The graphite oxide can exhibits the reversible specific capacities of 120 and 85 mAh/g with the high capacity retention at 50 and 100 mA/g.关键词
