These nanostructured SnO2 materials were accounted for to convey significantly upgraded particular limits with solid cycling secure qualities. With a specific end goal to mechanically support the volume development connected with the charge/release forms in the lithium-particle cells, the shaping of SnO2/graphene nanocomposites. Blossom-like SnO2/graphene composite is incorporated by a basic aqueous technique for high-limit lithium stockpiling. The as-arranged items are portrayed by XRD, FTIR, FESEM, TGA and Nitrogen adsorption/desorption.

The electrochemical execution of the blossom-like SnO2/graphene composite is measured by cyclic voltammetry and galvanostatic charge/release cycling. The effects demonstrate that the bloom-like SnO2 nanorod bunches are 800 nm in size and homogeneously follow on graphene sheets. The bloom-like SnO2/graphene composite presentations predominant Li-battery execution with substantial reversible limit, superb cyclic execution and great rate proficiency (Guo, Fang, Sun, Shen, Wang, & Chen, 2013). The Graphene nanosheets/SnO2 composites were orchestrated utilizing stannous chloride to restore the semi-diminishment graphene oxide (SRGO) under a straightforward aqueous decrease technique.

First and foremost graphene oxide was prereduced by glucose for a certain time to get SRGO, which keeps the great water-solvency of graphite oxide (GO) and has a great conductivity like graphene nanosheets. The higher electrostatic fascination between SRGO and Sn2+ makes SnO2 nanoparticles hard stay on the graphene sheets in the aqueous lessening methodology. The establishment component of the composite was researched by SEM, TEM, XRD, AFM and Raman. Also, the electrochemical practices of the Graphene nanosheets/SnO2 nanocomposites were considered by cyclic voltammogram, electrical impedance spectroscopy (EIS) and chronopotentiometry.
