Abstract

Two types of trigol reduced one pot synthesized graphene (TRG) based nanocomposites (SnO₂-TRG, and Fe₃O₄-TRG) are examined as potential anodes for Lithium ion battery (LIB) applications. The two specific systems represent different electrode reaction mechanisms, namely alloying, and conversion respectively. The high resolution transmission electron microscopy (HR-TEM) analysis confirms the uniform distribution of SnO₂ (~2 nm), and Fe₃O₄ (~8 nm) particulates on ultrathin TRG nanosheets and highlights the importance of surfactant free synthesis. The SnO₂-TRG, and Fe₃O₄-TRG exhibited the maximum reversible capacity of ~947, and ~1024 mA h g^-1, respectively. The results show that such graphene based composite materials can be effectively used as prospective anodes for LIB applications.
