摘要

Flower-like SnO₂/graphene composite is synthesized by a simple hydrothermal method for high-capacity lithium storage. The as-prepared products are characterized by XRD, FTIR, FESEM, TGA and Nitrogen adsorption/desorption. The electrochemical performance of the flower-like SnO₂/graphene composite is measured by cyclic voltammetry and galvanostatic charge/discharge cycling. The results show that the flower-like SnO₂ nanorod clusters are 800 nm in size and homogeneously adhere on graphene sheets. The flower-like SnO₂/graphene composite displays superior Li-battery performance with large reversible capacity, excellent cyclic performance and good rate capability.
