Abstract
Graphene oxide (GO)/polyaniline (PANI) composite are synthesized via in situ polymerization in the presence of grapheme oxide under acid conditions. The GO/PANI was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM) and electrochemical testing. The cathodes prepared using PANI and GO/PANI delivered initial discharge capacities of 78mAh/g and 104.4mAh/g ,respectively stable reversible capacities of 58.5mAh/g and 103.7mAh/g after 50 chargedischarge cycles. The GO enhances the discharge capacity of the PANI electrode material. GO/PANI is a good candidate as electrode material in lithium ion batteries
