dc.description.abstract Abstract Graphenothermal Reduction process is used to obtain exfoliated graphene oxide (EG)/iron (II) oxide (FeO) composite prepared at 650°C for 5h in argon. Structural and compositional analyses of the sample confirm the formation of EG/FeO composite. This composite shows a reversible capacity of 857mAhg < sup > -1 < /sup > at a current rate of 50mA g < sup > -1 < /sup > in the voltage range 0.005-3.0V versus Li. An excellent capacity retention up to 60 cycles and high coulombic efficiency of 98% are also observed. Characteristic Fe < sup > 2+/0 < /sup > redox peaks observed in Cyclic Voltammetry measurement are explained in correlation with lithium storage mechanism. Thermal, electrical and impedance spectroscopy studies of EG/FeO composite are discussed in detail. Comparative electrochemical cycling studies of EG/FeO composite with Fe < inf > 2 < /inf > O < inf > 3 < /inf > and Fe < inf > 3 < /inf > O < inf > 4 < /inf > materials prepared under controlled conditions are also discussed.
