GO was prepared using modified Hummers method. Few-layered nature of the exfoliated material was confirmed by electron microscopy, X-ray and electron diffraction, and Raman spectroscopy. Coin cells were fabricated using FLG as an anode and lithium metal as a counter electrode. The cells were tested using cyclic voltammetry and galvanostatic cycling techniques. FLG showed reversible capacity values of ~400 and ~250 mAh g -1 at current rates of 0.1 and 1 C, respectively. Columbic efficiency was more than 98 % while cycle to cycle capacity fading was less than 2 %. Maximum discharge or charging capacity was below 0.3 V, a preferable characteristic for achieving ideal anodic behavior. © 2013 Springer-Verlag Berlin Heidelberg.||Source Title:||Journal of Solid State Electrochemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/93703||ISSN:||14328488||DOI:||10.1007/s10008-013-2338-2|
