Fabrication of novel rugby-like ZnSnO3/reduced graphene oxide composites as a high-performance anode material for lithium-ion batteries

Fine ZnSnO3/reduced graphene oxide nanocomposites (ZSGNC) were successfully synthesized via a simple colloid flocculation method. Morphology analysis showed that the rugby-like ZnSnO3 nanoparticles (NPs) (~4nm in size) were well distributed on the reduced graphene oxide (rGO) sheets. The as-prepared ZSGNC manifested high specific capacity and improved cycling stability for a potential anode material in lithium-ion batteries (LIBs), which delivered an initial discharge capacity of 1691mAhg−1 at 100mAg−1 and retained 713mAhg−1 after 100 cycles. These results indicate that the ZSGNC is a promising anode material for high-performance LIBs.
