ABSTRACT

In lithium ion batteries (LIBs), materials that can store enough Li+-ions during charging are generally used as anodes. Among different anodic materials, this chapter focuses on graphene and it’s composite with Tin oxide (SnO2) as the best representatives of metallic and non-metallic anode materials. It discusses the different mechanisms and approaches proposed to address the problems associated with their electrochemical properties. Using a simple method involving the sonication and ultracentrifugation of graphite, graphene ink and Copper-supported graphene nanoflakes were used as an anode in LIBs. Recently, there have been attempts to combine graphene with other materials to make composite materials for an anode with improved performance. SnO2/graphene nanoribbon is a structural variety designed to address the problem of SnO2 aggregation and has been demonstrated to be a promising anode for high-energy LIBs. Due to their extremely small size, these structures are capable of undergoing expansion and contraction during conversion or an alloying and dealloying reaction with lithium ion.
