communication devices, portable electronic devices, andelectrical/hybrid vehicles, have attracted special attention inthe scientific and industrial fields due to their high electromotiveforce and high energy density. For an anode materialin LIB, graphite is usually employed as a standard electrodebecause it can be reversibly charged and discharged underintercalation potentials with reasonable specific capacity.1,2However, to meet the increasing demand for batteries withhigher energy density, much research attempt has been madeto explore new electrode materials or design novel nanostructuresof electrode materials.3-7 Especially, among thecarbonaceous materials, graphene-based materials could beone of the promising alternatives as an anode in LIB becausethese materials have superior electrical conductivities thangraphitic carbon, high surface area of over 2600 m2/g,chemical tolerance, and a broad electrochemical window thatwould be very advantageous for application in energytechnologies.8-12 Recently, we are quite successful in thecontrolled reassembling of exfoliated graphene nanosheets
