Graphene based nanocomposites for alloy (SnO2), and conversion (Fe3O4) type efficient anodes for Li-ion battery applications
Source abstract
Abstract
Abstract Two types of trigol reduced one pot synthesized graphene (TRG) based nanocomposites (SnO 2 -TRG, and Fe 3 O 4 -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 SnO 2 (∼2 nm), and Fe 3 O 4 (∼8 nm) particulates on ultrathin TRG nanosheets and highlights the importance of surfactant free synthesis. The SnO 2 -TRG, and Fe 3 O 4 -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.
