ABSTRACT
In the present chapter, we investigate and describe the performance of layered graphene sheets synthesized from camphor on the copper substrate Cu (111) as anodic material for lithium-ion battery. Detailed electrochemical studies of the synthesized single-layered graphene film (SLGR) and a few-layered graphene film (FLGR) were carried out and were successfully tested as anodic material for lithium-ion batteries (LIBs). The results show a robust and stable performance of graphene films for LIBs. The discharging/charging rate capacity of SLGR is better than FLGR is due to better island formation and defect-free structural bonding of carbons atoms in SLGR. The electrochemical studies like cyclic voltammetry and impedance spectra show an enhanced physicochemical behavior of SLGR as compared to FLGR. The observations are correlated with complete carbon bonding and a defect-free structure in SLGR as compared to FLGR. The formation of the island and the crystalline nature of layered graphene sheets play a vital role in LIBs’ performance.
